摘要:
Heating boiler intended to be used for burning straw, paper and similar fuel material in the form of compressed bales. The boiler is capable of supplying the material to be burned as a function of the heat requirements. It is necessary to provide optimum combustion conditions to maintain exhaust gas emission values within prescribed limits. The boiler is therefore provided inside its combustion compartment with a channel (2) wherein the compressed bales are dried and the slow distillation gas is removed to a large extent from the fuel. The bale supply channel (2) opens into a combustion chamber (4) enclosing the combustion compartment and preventing the flames from touching the water jacket (15) of the boiler.
摘要:
A fluid bed dryer comprising a drying chamber and a heating jacket contiguous with a drying chamber. The drying chamber and the heating jacket are each adapted to contain a bed of fluidizable particulate heat transfer material and each has a fluidizing gas inlet and an exhaust gas outlet. The drying chamber also has a feed inlet and a feed outlet. The fluid bed dryer may be used in a heat exchange system in combination with means for conveying a slurry comprising liquid and combustible waste solids to the feed inlet of the drying chamber of the fluid bed dryer; a reactor having a feed inlet, a reaction section, and a vapor exhaust port; conveyor means for transferring solids from the feed outlet of the drying chamber to the feed inlet of the reactor; conduit means connecting the vapor exhaust port of the reactor to the fluidizing gas inlet of the heating jacket of the dryer; and means for providing fluidizing gas to the fluidizing gas inlet of the drying chamber.
