Steam Boiler Repair Parts High Pressure Parts Bare Tube Economizer in ASME Standard
Product Details
Economizer is a mechanical device intended to reduce energy consumption, or to perform another useful function like preheating a fluid. The economizer is used for other purposes as well boiler, powerplant, and heating, ventilating, and air-conditionin(HVAC) uses are discussed in this article. In simple terms, an economizer is a heat exchanger.
Boiler economizer is the rear heating surface of the boiler, which is usually located at the outlet of the boiler. The economizer collects heat from the flue and increases the inlet temperature of the boiler through the waste heat of the flue gas. While reducing the exhaust temperature, it increases the inlet temperature of the boiler, reduces the thermal stress caused by the temperature difference between the drum wall and the feed water, and reduces the shrinkage and expansion of the drum. The economizer of our company generally adopts 20 medium and low pressure boiler tubes, 20g seamless steel tubes or ASME grade steel tubes. It reduces the temperature of flue gas, recovers heat to the maximum extent, and improves the overall efficiency of the boiler, so as to help customers reduce fuel consumption and reduce the cost of the boiler.

Application
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
When you purchase a thermal fluid heater, the cost of fuel to operate the heater is a major concern. The amount of fuel needed is related to the thermal efficiency of the heater. Increasing its thermal efficiency reduces the amount of fuel needed as well as operating costs.
