The economizer (English name Economizer) is a device installed in the lower part of the boiler tail flue to recover waste heat. The boiler feed water is heated to the heated surface of the saturated water under the pressure of the drum. Because it absorbs the heat of the low temperature flue gas, It reduces the flue gas exhaust temperature, saves energy and improves efficiency, so it is called a economizer.
Heat pipe heat exchanger
Heat pipe is a kind of heat transfer element with high thermal conductivity. It transfers heat through evaporation and condensation of working fluid in a fully enclosed vacuum tube shell. It has extremely high thermal conductivity, good isothermal properties, and heat transfer on both sides The area can be changed arbitrarily, heat can be transmitted over long distances, and temperature can be controlled. Disadvantages are poor resistance to oxidation and high temperature. This disadvantage can be solved by installing a set of ceramic heat exchanger at the front. The ceramic heat exchanger better solves the problems of high temperature resistance and corrosion resistance.
Star ash discharge valve
The star-shaped ash discharge valve is divided into a round star-shaped ash discharge valve and a square star-shaped ash discharge valve according to their external structure. Its advantages are: stable and reliable work, uniform and accurate discharge, optimized structure, small size, good sealing performance, and maintenance Convenient, lightweight, energy-saving, long life and more. It is also one of the indispensable equipment for drying, dust, particles, and solid conveying equipment.
