This report reviews the design of the prototype coal-fired space heating system for residential applications. The entire unit comprises the following key components, namely: a combustor, heat exchanger, and ash collector. The design of this optimized combustor consists of a short refractory quarl, swirl stabilized burner and a double shell combustion chamber made of stainless steel. The burner was designed to burn dry ultrafine, high volatile bituminous coal at a nominal firing rate of 100 {times} 10{sup 3} Btu/hr and 30 percent excess air. The combustor was designed to utilize the combustion air as cooling air for the chamber. The combustion chamber was designed to yield a gas phase residence time of approximately 1 second. The heat exchanger is a commercial design, by the Will-Burt Company. The unit is engineered for minimum pressure drop and maximum heated surfaces for heat transfer. Particulate laden flue gas clean-up is achieved by an ash collector which consists of primarily a bag filter and is designed for easy ash removal and cleaning. 2 refs., 12 figs., 2 tabs.
