  • Combustion, Pyrolysis, Gasification, and Liquefaction of Biomass …

    Pyrolysis of biomass is a particularly attractive process if all three products - gas, wood tars, and charcoal - can be used. Gasification of biomass with air is perhaps the most flexible and best-developed process for conversion of biomass to fuel today, yielding a low energy gas that can be burned in existing gas/oil boilers or in engines.Get Price

  • Challenging Boiler Tube Cleaning Problems Can be Solved

    One university in Virginia decided to try burning cheaper oil to save money—waste oil, in fact, which they were able to obtain at far lower costs than the standard fuel. Eventually, the low quality of the waste oil created huge problems in the form of a thick, hard layer of residue coating the exterior of the boiler tubes.Get Price

  • How to Destroy a Boiler -- Part 1

    A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and will continue to produce some heat.Get Price
