Flue Gas Waste Heat Boiler Thermal Efficiency Calculation
1.1 Bituminous And Subbituminous Coal Combustion
Any exhaust gas stream with temperatures above 250°F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate. Typical examples include plant process heating, combustion air pre-heating, boiler feedwater pre-heating, and building heat.

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.
demand of the manufacturing products provided the manufacturer itself performs the NDT. Article 14 Specific requirements for manufacture licensing of level-D boiler 1.

Flue Gas Heat Recovery Systems (FGHRS) take advantage of heat within waste flue gases resulting from the combustion of gas in your boiler. This recovered heat is used to preheat the cold water entering the boiler, thereby lowering the amount of energy needed to warm the water up to the required level.
For most heating equipment, a large amount of the heat supplied is wasted in the form of exhaust or flue gases. These losses depend on vari-ous factors associated with the design and operation of the heating equipment. This technical brief is a guide to help plant operators reduce waste heat losses associated with the heating equipment.
