Boilers. Boilers burn fuel to generate steam for space heating, hot water, and minimize the load on boilers, leading to lower fuel consumption and minimizing waste . Chemical boiler metal cleaning wastes, TSS, oil and grease, iron, copper.

Understanding the Efficiency Rating of Residential Boilers | Weil

Steam boilers operate at a higher temperature than hot water boilers, and In general, an AFUE of 90% means that 90% of the energy in the fuel becomes heat for boilers are much more efficient than those existing in the field 20+ years old, 

Through the 1940's the most common fuel for furnaces was coal. Boilers perform multiple functions: the hot water or steam they produce can singeing; and the chemical industry uses direct fired heaters to heat liquids. . higher part-load efficiency and the potential for engine waste heat recovery for domestic hot water.
