The Firebox LPD CG (Low Pressure Chain Grate) design is suitable for applications to produce low pressure steam or hot water in ranges from 3,450 - 20,700 lbs/hr (3.4 mm BTU - 20 mm BTU) output at 15 PSI steam or 30 PSI hot water.
This system is designed by HBC to combine the best technologies from the "old school" of coal combustion and the latest advanced combustion control technologies. The new HBC chain grate-type stoker system permits either bituminous coal washed singles or smalls to be combusted in an efficient manner with the added advantage of automatic de-ashing. This combination is particularly suitable for residential and industrial heating and process steam applications. The boiler vessel is a three-pass fire tube firebox design that inherently provides an extended water membrane in the furnace area greatly reducing the amount of refractory required.
