Abstract. Heat recovery steam generators (HRSGs) are important components for industrial waste heat recovery, and any changes in their design directly affect the performance of the steam cycle, and thus the performance of the combined cycle power plant.
Waste heat boilers are the significant energy saving equipment, utilize the heat in flue gases from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the waste heat boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine
Waste Heat Recovery Boilers ( WHRB ) Waste heat boilers are generally water tube boilers in which the hot exhaust gases from gas turbines, incinerators, etc., pass over a number of parallel tubes containing water. The water is vaporized in the tubes and collected in a steam drum from which it is drawn off for use as heating or processing steam
With over 1200 waste heat recovery units to date, HDI has unmistakable expertise in this industry. HDI offers a few different types of waste heat boilers, watertube and firetube. Watertube Boilers: Designed similar to our HRSGs, but are refractory lined, and typically have tubes that can handle dirtier gasses than in the power generation industry.
Economizers for Any Application. The E-Tech economizer is essentially a finned tube heat exchanger installed in the boiler flue exhaust stack. Hot flue gases pass over the finned tubes as boiler feedwater circulates inside the tubes. This preheats the feedwater, recovering otherwise wasted heat from the escaping flue gas.
Usually higher the temperature, higher the quality and more cost effective is the heat recovery. In any study of waste heat recovery, it is absolutely necessary that there should be some use for the recovered heat. 5/24/12. e.g. preheating of combustion air, space heating, or preheating boiler feed water or process water.
There are mainly two types of industry boilers - there are water tube boiler and fire tube boiler if divided from inner structure.These are the main two types of boiler but each of the types can be sub divided into many different types of boiler.
