Energy-saving type coal-fired boiler

Abstract

The invention relates to the technical field of energy-saving environment-friendly equipment and discloses an energy-saving type coal-fired boiler which comprises a base. A boiler body is fixedly installed on the top of the base. A fixing plate is fixedly installed on one side of the bottom of an inner cavity of the boiler body. A shaft rod is fixedly installed on the middle portion of the fixingplate. The outer surface of the shaft rod is fixedly sleeved with an ash receiving plate. A first fire grate receives coal fragments falling off from a second fire grate, the coal fragments can be combusted for second time conveniently, coal resources can be combusted beneficially and fully, energy sources are saved, the energy source utilization rate is increased, a transverse rod drives a cushion block to move downwards, the cushion block extrudes a compression spring downwards, elastic deformation of the compression spring is utilized for generating reverse acting force, the ash receiving plate is turned over elastically along the shaft rod, waste slag on the ash receiving plate can be cleared beneficially and effectively, the situation that when direct manual clearing is used, the waste slag cannot be eliminated thoroughly, and the working efficiency is improved beneficially.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environmental protection equipment, in particular to an energy-saving coal-fired boiler. Background technique [0002] A coal-fired boiler is a boiler whose fuel is coal-fired. It refers to thermal energy power equipment that heats heat medium water or other organic heat carriers, such as heat transfer oil, to a certain temperature or pressure after burning coal in the furnace to release heat. Coal boilers are mainly classified according to their uses, including coal-fired boiling water boilers, coal-fired hot water boilers, coal-fired steam boilers and coal-fired thermal oil boilers. [0003] As my country's requirements for safety, energy saving and environmental protection are increasing year by year, how to further accelerate the development of energy saving and emission reduction work under the situation of promoting the healthy and steady development of the industry and ensuring th...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides an energy-saving coal-fired boiler, which has the advantages of secondary combustion of coal fragments, energy saving and emission reduction, and convenient ash discharge, which solves the problems of most industrial boilers in terms of energy saving and emission reduction. The effect is negligible, the coal enters the furnace for combustion, and the small coal or slag is not completely burned, and enters the waste residue chamber from the grate, which cannot make full use of coal resources. In addition, the coal ash in the waste residue chamber is not easy to clean, and manual shoveling is required out, increasing the burden on the staff
