Agricultural Anaerobic Digesters: Design and Operation

Dec 01, 2016 · The manufacturer's rating for boilers indicated a boiler efficiency of 0. 7 with LP gas and 0.78 with natural gas. The value of 0.58 was used in calculating the needed boiler capacity due to intermittent and low-load operation. A boiler with a rated input value of 66,000 Btu/hr (19.5 kW) was selected for the Penn State digester installation.

Central heating - Wikipedia

Overview. Central heating differs from space heating in that the heat generation occurs in one place, such as a furnace room or basement in a house or a mechanical room in a large building (though not necessarily at the geometrically "central" point). The heat is distributed throughout the building, typically by forced-air through ductwork, by water circulating through pipes, or by steam fed
