A furnace arch of an industrial floor-fired boiler with adjustable angle

Abstract

The invention discloses an angle-adjustable industrial layer combustion boiler furnace arch. The angle-adjustable industrial layer combustion boiler furnace arch comprises a layer combustion furnace inner wall, a front arch and a rear arch, wherein a front arch groove and a rear arch groove are separately formed in the front and rear ends of the layer combustion furnace inner wall, a front arch clamping end and a front arch movable end are separately arranged at the two ends of the front arch, a rear arch clamping end and a rear arch movable end are separately arranged at the two ends of the rear arch, and rear arch side walls are arranged on the two sides of the rear arch. The front arch clamping end is arranged in the front arch groove, the front arch movable end is connected with an adjusting device, the adjusting device penetrates through the front end of the layer combustion furnace inner wall, and the adjusting device is used for pulling the front arch to rotate around the frontarch clamping end. The rear arch clamping end is arranged in the rear arch groove, the end of the rear arch movable end is connected with a plurality of movable blocks, a lifting device is arranged atthe bottom ends of the rear arch side walls, and the lifting device is used for pushing the rear arch to rotate around the rear arch clamping end. The angle-adjustable industrial layer combustion boiler furnace arch can be suitable for combustion of different coals, improves the combustion effect, saves energy, is environmentally friendly and has high adaptability.

Description

technical field [0001] The invention relates to the technical field of industrial boilers, in particular to an angle-adjustable industrial floor-fired boiler arch. Background technique [0002] At present, from the perspective of energy planning for the next 10-30 years, coal still occupies a dominant position in my country's primary energy consumption. The layer-fired boiler refers to placing the fuel on a fixed or moving grate to form a uniform material layer with a certain thickness. The air enters from the bottom of the grate and carries out combustion reaction through the fuel layer. . Because of its simple operation, high degree of mechanization, and convenient operation and maintenance, it is widely used. It is an important energy-consuming equipment in the field of industrial and central heating in my country. It consumes about 400 million tons of standard coal annually, accounting for 15% of my country's total coal consumption. %. [0003] However, the design of m...

AI Technical Summary

Problems solved by technology

[0003] However, the design of my country's layer-fired boilers is mainly based on foreign design experience, without considering the characteristics of the actual combustion coal. Due to poor ignition conditions and manual operation to stir the fire, it is not suitable for burning water, ash, and strong coking. Coal, coupled with the lack of technical knowledge of boiler operators, leads to low actual operating efficiency of boilers and high emissions of nitrogen oxides, which is an important source of air pollutants in concentrated urban residential areas in my country
