John and all    (He sent to Stoves list, so I repeat it in this reply to 
Stoves and Gasification lists.

My reply is below.

John, I like the terms "producer gas" and maybe the term "gas producer" 
(same thing as "gasifier").   The GPCS is good also, but only because it 
uses the word combustion in reference to a process that goes from biomass 
(or fossil-fuel coal) all the way to energy plus H2O and CO2 (plus wastes)

Note that you then choose to use the expression "straight combustion", 
thereby showing the need to constantly clarify which of many vague types of 
"combustion" you wish other people to understand.    What is "straight 
combustion" or any other combustion that is defined without using the word 
"combustion" or burning?
