1982/1/1 · Conclusions This study indicates that NO emissions from spreader stoker fired coal furnaces are the result of relatively high conversions (25-45%) of the fuel nitrogen evolved from particles less than 0.11 inches in the suspension phase and low conversions (5 to 15%) of fuel nitrogen from the bed combustion. In the suspension phase, nitrogen is Get Price
The chain grate stoker and travelling grate stoker have a good structure. Stoker boiler types may be categorized depending on the kind of fuel fed into the furnace and the manner of fuel feeding into the furnace. To categorize stoker boilers, they may be divided into chain-gate or travelling-gate stoker boiler and spreader-gate stoker boiler.Get Price
