The Coalmiser HPD (High Pressure) design is suitable for applications to produce high pressure steam or hot water in ranges from 5,000 - 40,000 lbs/hr (4.8 mm BTU - 39 mm BTU) output from 150 up to 250 PSI.
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 industrial heating and process steam applications. The boiler vessel is a three-pass fire tube design incorporating a wet back turnaround that eliminates the need for rear door refractory.
