Abstract

The invention discloses a method for smoke screen protection at the smoke side of a boiler. The problem that a specific heating surface of an existing boiler is prone to being corroded and abraded is solved. The method comprises the following steps of determining an area to be subjected to smoke screen protection; arranging an air curtain device; and solving an unknown number n according to a formula, namely, determining the number of arranged protection tubes according to the area to be subjected to smoke screen protection. The method has the beneficial effects that a smoke protection layer is formed on a heating surface or a specific area needing to be protected through the air curtain device, and the heating surface or the specific area is protected through protection of the protection layer, so that direct contact with smoke is avoided, erosive wear and corrosion are avoided, the safe operation period of equipment is greatly prolonged, the stability and continuity of the boiler or the device are improved, and the service life of the product is long.

Description

technical field [0001] The invention relates to the field of protection of boiler heating surface wall temperature or a specific area, in particular to a method for smoke screen protection of boiler flue gas side. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. Boilers are classified according to the type of fuel or energy. When the boiler burns different fuels, it is called a boiler of that type of fuel or a mixed-fired boiler of two fuels. The fire bed combustion boiler is a boiler in which the fuel is placed on the material bed and is called a grate furnace or a layer combustion furnace. The fuel of chamber-fired boilers is burned in the furnace chamber or furnace, generally including pulverized coal boilers, fuel oil, gas-fired boilers...
