Gas Phase Alkali Chlorides and Deposits during Co-Combustion of Coal …

Straw pellets have been co-fired with a bituminous coal with a high chlorine content. The tests were carried out in a 12 MW circulating fluidized bed (CFB) boiler located at Chalmers University of Technology in Sweden. The tests focused on variation of the ratio of straw to coal in combination with different feeding rates of limestone to the bed. Three test series were carried out: Lime

A first and still major purpose of the LT CFB gasifier is "indirect" co firing of difficult biomass and waste fuels at coal fired power plants. In this case simple hot gas cleaning prior to the boiler can be based on just a hot secondary cyclone, i.e. cooling of the product gas is avoided.
