  • Boiler Tube sliding block

    Boiler Tube sliding block

    Boiler Tube sliding block, also known as Sliding pair, is composed of two components, which can only move in a certain direction. It has the function of keeping the tube platen flat in the platen superheater and preventing the tube from being out of line and dislocated and the formation of coke residue. The sliding pair is generally made of ZG16Cr20Ni14Si2 material.

    Boiler water cooling wall tube of power plant

    The water cooling wall tube is the only heating surface in the evaporation equipment. It is a radiation heat transfer plane composed of continuously arranged tubes. It is close to the furnace wall to form the four walls of the furnace. Some large-capacity boilers arrange part of the water-cooled wall in the middle of the furnace. The two sides absorb the radiant heat of the flue gas respectively, forming the so-called double-sided exposure water wall. The inlet of the water cooling wall pipe is connected by the header, and the outlet can be connected by the header and then connected to the steam drum through the air duct, or it can be directly connected to the steam drum. The inlet and outlet headers of the water wall on each side of the furnace are divided into several, the number of which is determined by the width and depth of the furnace, and each header is connected with the water wall pipes to form a water wall screen.
