Embodiment Construction

[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0027] Depend on figure 1 combined with Figure 2-5 As shown, a method for protecting a smoke screen on the flue gas side of a boiler, the method comprises the following steps:

[0028] Step 1, clarify the target and determine the area 4 that needs to be protected in the boiler, so as to determine the area to be protected by the smoke screen s Y ;

[0029] Step 2., setting an air curtain device, the air curtain device 1 includes a bellows 2 and a protection pipe 3, and the bellows is connected with a protective gas source; specifically, the bellows 2 is provided with a joint 5, so the The protective gas source described above is connected to the bellows through a joint. More specifically, the protective gas source can be air. The protective gas source can be a specific component gas, more specifically, the specific component gas is nitrogen.

Abstract

A method for smoke screen protection on the flue gas side of a boiler. It solves the problem that the specific heating surface of the existing boiler is easily corroded and worn. It includes the following steps: determining the area to be protected by the smoke screen; setting the air curtain device; according to the formula: finding the unknown n, that is, determining the number of protection pipes arranged according to the area to be protected by the smoke screen. The beneficial effect of the present invention is that the smoke protection layer is formed on the heating surface or specific area to be protected by the air curtain device, and the heating surface or the specific area is protected by the protection of the protective layer, so as to avoid direct contact with the smoke and avoid The occurrence of erosion wear and corrosion greatly prolongs the safe operation period of the equipment, thereby improving the stability and continuity of the boiler or device, making the product long service life.

Description

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