Dear Saravanakumar Are you intending that the downdraft gasifier produce charcoal, or burn it? If it is producing some, how much?
Whatever char you take out at the end of a burn you subtract from the total heat that was available in the original fuel. I expect the thermal efficiency would rise because you can run a lower excess air ratio, perhaps 1/2 or less. That will make for the loss of some of the energy that passes out in the form of char. If you are burning the char as a gas, the system efficiency should rise by the difference excess air makes. Regards Crispin +++++++++ Dear All, Wood Fired Boiler Boiler capacity = 3TPH Pressure = 2.5kg bar pressure Fire wood consumption = 1 ton of wood combustion / hr Steam production = 2.5 ton /hr If we change the above into the down draft Gasifier based gas fired boiler, how about the Gasifier Capacity = ? Fire wood consumption = ? Steam Production = ? Please let me know, A.
