Customized Boiler Economizer Coal Fired Energy Saving System HD Boiler

Product Description

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.

Parameter

*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.

Details

1.Economizers must be sized for the volume of flue gas, its temperature, the maximum pressure drop allowed through the stack, what kind of fuel is used in the boiler, and how much energy needs to be recovered.

2.Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler.

3.Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.

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.
