David Ashley Tillman, born on February 24th 1944 in Hartford, CT passed away on August 9th, 2020 in Peoria,AZ.
David is survived by his son and daughter in law, Darek and Dianne Tillman. He also was the proud grandfather of Trevar and Taylar Tillman. He leaves behind his sister Susan Cahee.
David joins his wife of 30 years, Mildred Tillman, to be with our lord.
David preferred to be called “Dave”, and so will be for the reminder of this passage.
Dave lead a very accomplished and interesting life. He was raised in rural New England and attended the University of New Hampshire where to the surprise of many of his friends, he majored in social work.
He eventually made his way to Washington DC, working in the famous Watergate building. This is where he would meet Millie, the love of his life.
From there he moved his family to Seattle to pursue his doctorate from the University of Washington. Ever the humble man, he did not like being referred to as “doctor”. He would always say “I’m Dave”. This launched his career in the world of combustion, becoming renowned in his field of combustion and power generation. He received many awards and accolades, including the prestigious Alex Dow award from Detroit Edison.
Dave authored and co-authored over two dozen books. His son was surprised to find several of his books in the Northern Arizona library where Darek was a student.
Dave was an avid dog lover and advocate. He raised several dogs throughout his life and even rescued a couple of St. Bernards. If there were dogs nearby, you could bet they would find him and they would immediately bond.
Dave also had a consuming passion for building model train layouts. In one house in Yuba City, CA Dave actually built a layout in his living room. It was approximately 40 linear feet and the first thing you would see upon entering his house. He gave talks on modeling at the annual railroad modelers convention.
He always made time for his family by making one or two trips to AZ every year. He always made sure to watch his grandchildren compete in athletics. He even once helped by being on the chain gang at one of Trevar’s football games. He was completely thrilled when Taylar took up competitive tennis and helped supply racquets. He was, of course, most proud of how competitive his grandchildren were in the classroom.
His faith in Christ helped guide his generosity to others. Dave was always willing to lend a helping hand or just a shoulder to cry on. He will be missed by many and leaves behind quite the legacy.
Services will be held at Darek and Dianne’s house at 9321 W Yukon dr, Peoria AZ on Saturday August 15th at 3pm.
In lieu of flowers, please donate to your local humane society. That would make Dave very happy.

He was very good about putting up with my ignorance about power plants while we talked about model railroading. And I learned a lot more as we dismantled his layout over the winter. I will miss him greatly. My condolences. less

He was a very inspiring person who helped me through my graduation project, guided me on giving public speeches and led me to power plant field. I remembered he always sat in the back of the classroom directing my tones while i practiced my speeches. Also Dave was a great host for a BBQ meal. Thank you Dave. May your soul rest in peace. less

I met him in 1992 when his company in Sacramento submitted a winning proposal to EPRI in response to our requesting proposals to assess biomass power technologies. (Stan Harding was part of the team that Dave proposed.) The company was Envirosphere, later Foster Wheeler, and eventually Foster Wheeler in New Jersey. I learned later that the excellent winning proposal was what he had personally written while on a long flight to Korea.
Dave became a friend as well as a contractor, and both our technical collaboration and our friendship continued after 2003, after I was an independent consultant rather than an EPRI project manager. After the 2016 election politics was added to our conversation topics, and then, a year or so ago, Christian faith and Bible texts were also added. His most recent long phone call to me included a critique of a biomass energy (biofuel) technology I was working on, and he also made comments on what I had written for my discussion group at First Presbyterian Church in Palo Alto. He was more interested in the Bible and the church group. In fact, about six months ago at his request, I had bought a Bible for him, as an online purchase delivered to Darek’s address, a large-print edition and King James Version. This was per Dave’s instructions. He had said several times, “I can read Elizabethan English.”

We also knew him in our family as "Papa Dave", when my children Genevieve and Ethan were little we lived not far away from him in Pennsylvania. They loved his trains and were equally in love with and terrified of the giant dogs. He always treated my children like his own grandchildren. All of our love and condolences, Elizabeth Ashley (Lundberg) Holtsclaw and the Holtsclaw family. less

He was a genuinely caring, giving, hard-working and fun-loving person who represented the best f our species. I am so glad that Dave and I were able to connect over the past few months. Our long phone conversations meant a lot to me. To Darek, Dianne, Trevor and Taylor - May you be strong in your time of sorrow and may the good memories bring you peace. less

Over the years our friendship grew, and during this time, not only did I come to appreciate the depth of his professionalism and knowledge - he was truly what I consider to be a giant in our industry. Even moreso, I came to glimps his caring heart for his fellow man, and particularly, for the down-trodden.
I was struck at how he was constantly looking to help the less fortunate and less abled. this shown through one day when we stopped at a Walmart. Dave would never go to the self-checkouts, but he insisted in standing in line, solely to make the effort to protect the cashier's job - he knew that many of those folk were not capable of jobs beyond the skill level needed to run the cash register, so he made it his business to never use the self-checkouts in fear that it might replace someone's job.
I saw Dave, time and again, come around people just to encourage them when they needed a lift, be it a waiter or waitress at a restaurant or a young father-less boy who needed a father figure to encourage, guide and encourage.
Dave knew his Lord Jesus Christ and truly lived out the Christian life. Dave will be sorely missed by us here, but he leaves a legacy that will live on in the lives of so many of us who knew him. less

I learned so much from Dave. Over time we developed a strong friendship. My condolenses on his passing and our thoughts are with his family and friends. The world has lost a good man and will be the worse for it. less
I met Dave few years ago at Detroit Edison. I found Dave to be a great mentor, an intellect, and a very humble down to earth individual. My thoughts and prayers are with the family. May his soul rest in peace.

He was working on solving some operational problems with the new SCR's that were installed at Monroe. He was a "one of a kind" individual that brought some much to the the professional and personal table. He was constantly teaching whether it was co-ops or seasoned engineers. That was his true passion and love. Always sharing his knowledge and teaching others on how to completely solve a problem. He loved coming in on the back shift and sitting with the operators running the units at Monroe Power Plant.
I was able to hire Dave to work in our Engineering Department at Monroe. Shortly after this Dave and I were at an conference and folks came up to me and wanted to know have I managed to hire Dave ! Dave moved in down the street from me and my family welcomed him with open arms. he became a regular fixture at all of our family gatherings. Dave you will be truly missed by everyone that you touched. I'm glad you will be able to spend eternity with Millie, the love of your love. God spend on your next journey.

Dave became my mentor and guidance. He treated me like family and supported me in every way he knew how to. I owe my professional life and much of my adult growth to Dave. Dave, I hope you are loving your time in heaven with Millie, Dozer and so many of the other dogs that you so much loved and took in. We will miss you down here and may some day we meet again so that we can enjoy those barbecue steaks that you so love grilling on the warm summer days.

To the Coal Quality Issues group, it is with great sadness to announce the passing of one of our dear colleagues, Dr. David A. Tillman who passed away Sunday night in Phoenix, AZ from complications of the COVID-19 virus. Dave was a very considerate, generous, and exceptional combustion man. He enjoyed solving-real world problems! Dave has been a good friend for many years. We will miss his big personality and warm-hearted humor. Our industry will miss his insights and pragmatic approach to utility boiler combustion problem-solving.

I have had the privilege of working with Dave for over 30 years. He has been a mentor and great friend. We worked on some excellent projects together and Dave always took the opportunity to help me understand better what was occurring during whatever tests we were doing. However, he did have a fun streak also! One of our early projects was a biomass cofiring demonstration in the eastern US. He took me to a Cracker Barrel for breakfast. As we did not have any of those restaurants out west (at that time), I hadn’t ever been to one. He suggested I order the sampler (?) and smiled. Well it came, consisting of 4 plates of every conceivable breakfast food imaginable: oatmeal, toast, bacon, sausage, ham, eggs, pancakes, grits, etc., etc., etc. He just burst out laughing when I looked at it all. I couldn’t finish it; but I was always weary after that of him ordering for me anywhere, anytime!
One of Dave’s many strengths was his completeness in solving problems and in writing his many books. A look at the references in any chapter of any book demonstrates his desire to understand all sides of a topic and provide his expert opinion on a given issue.
I will personally miss the wonderful associations I had with Dave over the years. I still marvel at his railroad display in his house. It was phenomenal; complete with model power plants, including: boilers, scrubbers, baghouses, cooling towers, etc. He designed and built most of his models himself. He was a true artisan.
Darek and family, we know Dave is in a better place, free from physical limitations. I, as I am certain you do, look forward to meeting him again.

Thanks for sending that on Stan. Dave was a giant in energy and combustion fuels indeed. So sorry to hear that COVID-19 cut his life short.
Chris Zygarlicke, University of North Dakota Energy and Environmental Research Center, USA
I am so very sorry to learn this; I've known him for ages (he might even go as far back as the slurry days), and he was an active contributor to the conference. He was a lovely man and he had great ideas and taught Workshops and went after papers for sessions. For many years he brought his wife whose name is escaping me right now (I think it was Annie) to the conferences. I can still see the two of them in my mind's eye.
I will let the entire committee know about this.
This is so sad and because it is this awful disease it seems even worse.
