Mobile coal-fired fluidized bed power unit

摘要

A mobile coal-fired fluidized bed furnace system (10) is provided for generating steam to power a locomotive. Coal is combusted within the fluidized bed furnace chamber (30) in the fluidizing air to produce a hot flue gas which pass from the furnace chamber (30) through a boiler tank (90) and an economizer (34). The steam generated in the boiler bank and the walls of the furnace chamber is collected in steam drum (40) and passed therefrom through an in-bed superheater (100) and thence to the power generating means (22) to produce the power which drives the locomotive.
