Boiler and method for enabling boiler to operate

Abstract

The invention discloses a boiler and a method for enabling the boiler to operate. The boiler comprises a boiler device composed of a combustion system and a heating system. The combustion system comprises a fixed frame fixedly arranged on the left side of the end face of the top of a base and a combustion furnace integrally arranged at the top of the fixed frame. A combustion cavity is arranged inthe combustion furnace. Spiral feeding cavities extending up and down are symmetrically arranged at the positions, on the left side and the right side of the combustion cavity, in the combustion furnace. A spiral feeding paddle is mounted in the upper end wall and the lower end wall of each spiral feeding cavity in a running fit manner. Feeding boxes are fixedly arranged on the end faces of the left side and the right side of the combustion furnace. A feeding groove communicating with the corresponding spiral feeding cavity is arranged in each feeding box, wherein an opening of each feeding groove is upward. A first mounting cavity extending left and right is arranged at the inner bottom of the fixed frame.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler and a method for operating the boiler. Background technique [0002] There are more than 500,000 industrial boilers in my country, and the annual coal consumption is about 1 / 3 of the total coal consumption in the country. The environmental pollution caused by coal-fired industrial boilers is very serious, and a large number of industrial boilers must be replaced with clean energy. According to my country's biomass resource conditions, the use of agricultural and forestry residues as boiler fuel is environmentally friendly and renewable. Research on biomass combustion technology for industrial boilers and development of biomass fuel boilers will help save conventional energy and optimize my country's energy structure. It is of positive significance to reduce environmental pollution. However, the biomass boilers currently on the market are simple in structure and complex in...

Problems solved by technology

According to my country's biomass resource conditions, the use of agricultural and forestry residues as boiler fuel is environmentally friendly and renewable. Research on biomass combustion technology for industrial boilers and development of biomass fuel boilers will help save conventional energy and optimize my country's energy structure. Reducing environmental pollution has positive significance. However, the biomass boilers currently on the market are simple in structure and complex in operation, and cannot realize automation in the process of feeding, ash removal and heating, which greatly increases the labor intensity and greatly reduces the energy consumption. Combustion efficiency has major disadvantages and needs to be improved
