Problems solved by technology

[0004] The present invention solves the problem that a large amount of material produced by the combustion of the existing circulating fluidized bed boiler scours the heating surface of the furnace, which causes serious corrosion of the water wall of the boiler and affects the safe operation of the boiler. During welding, the welding efficiency is low, the quality of the welding surface is poor, the labor intensity of the workers is high, the working environment is harsh, and the radiation to the human body is large, so a welding device for the water wall of the circulating fluidized bed boiler is provided

Abstract

The invention relates to a cladding device for a water-cooling wall of a circulating fluidized bed boiler, aiming at solving the problems that the existing circulating fluidized bed boiler produces a great deal of material during combustion, and the heating surface of a hearth is scoured by the material, so that the water-cooling wall of the boiler is seriously corroded, and the safe running of the boiler is influenced; and when being used for cladding the water-cooling wall of the circulating fluidized bed boiler, the traditional cladding technology has the problem that the cladding efficiency is low, the quality of the clad surface is poor, the labor intensity of workers is high, the work environment is poor and radiation to the human body is high. A melting gun swing device is arranged at one side of the upper end of a connecting plate, and a driving motor is arranged at the other side of the connecting plate; the driving motor is connected with the melting gun swing device in a transmission way; the front end of the melting gun swing device is provided with a melting gun; and the driving motor is connected with a computer by a control circuit. The cladding device is used for cladding the water-cooling wall of the circulating fluidized bed boiler.

Description

technical field [0001] The invention relates to a cladding device for a water wall of a circulating fluidized bed boiler. Background technique [0002] Circulating fluidized bed boiler is an environmentally friendly boiler using advanced combustion technology. Compared with other types of boilers, it has wide fuel adaptability, low desulfurization cost in the furnace, low pollutant emissions, high combustion efficiency, and large load regulation ratio. The unique advantages such as the comprehensive utilization of ash and slag have become the most successful clean combustion technology in the practical process. The fuels used range from petroleum coke with almost no ash content to oil shale and coal gangue with extremely high ash content, from biomass such as straw, which is mainly produced by energy, to lean coal and anthracite with very low energy content. However, due to the structure of the circulating fluidized bed boiler, the combustion method and the flow characteris...
