The boiler economizer acts as a waste heat recovery device, ensuring that this heat does not go unused. Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam.

Nov 15, 2019 · Recovering waste heat from boiler exhaust flue gas is an effective way to improve energy utilization efficiency and reduce coal burning pollution of coal-fired power plant (CFPP). The low-pressure economizer (LPE) is the most widely employed in waste heat recovery from boiler exhaust flue gas.
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%.
Boiler Economiser (Sometimes Called Economizer) is the Energy improving device that helps to reduce the cost of operation by saving the fuel. The economizer in Boiler tends to make the system more energy efficient. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.
It is possi- ble to generate an electrical output of up to 11% of the main engine power by utilising this exhaust gas energy in a waste heat recovery system compris- ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating.
Aug 23, 2016 · Heat is removed from the flue gas through the use of economizers and air preheaters, but condensing water (and acid gas) is a limitation in how low the temperature can be taken. … Flue Gas Waste …

Mar 04, 2020 · In steam power plants it captures the waste heat from boiler stack gases (flue gases) and transfers it to the boiler feed water; Air-side economizers HVAC (Heating, Ventilation and Air Condition) can save energy in buildings by using cool outside air as a means of cooling the indoor space.
Products > Waste Heat Recovery Boilers / Heat Recovery Steam Generators and HTF Recovery Boilers. Application: Allow steam generation (saturated or superheated) and superheated water from flue of furnaces, gas turbines, waste liquid incinerators (HCL, H2SO4) or waste gas incinerators (Off-gas, biogas, SH2…), fuel-oil engines (2 stroke or 4 stroke), gas engines in cogeneration plants.

potential sources of waste heat? If you have any of the below in your building and you have direct control of them, then you should go to the building heating, cooling and ventilation section and work through the checklist to see whether there is the potential for heat recovery. • A boiler providing space heating or hot water.
Economizer: In case of process boilers, waste heat in the exhaust gas is passed along a recuperator that carries the inlet fluid for the boiler and thus decreases thermal energy intake of the inlet fluid. Heat pumps: Using an organic fluid that boils at a low temperature means that energy could be regenerated from waste fluids.
