Abstract

The invention relates to a coal-fired boiler, in particular to a coal-fired boiler convenient to improve coal combustion efficiency. The coal-fired boiler solves the problem that coal input by an existing coal-fired boiler is different in size, the situation that the coal combustion efficiency is low is easily caused. A coal crushing device is mounted at a coal inlet of a coal-fired boiler body, a mounting frame is mounted on the coal inlet of the coal-fired boiler body, a coal outlet is formed in the lower end of the mounting frame and located in the coal inlet of the coal-fired boiler body, a crushing barrel is mounted at the upper end of the mounting frame, a coal inlet pipe is installed at the upper end of the crushing barrel and communicates with a crushing net, the crushing net is embedded into the crushing barrel, a gap is reserved between the crushing net and the crushing barrel, the upper end of the coal outlet communicates with the crushing barrel, a motor is installed on the mounting frame, an output shaft of the motor is connected with a crushing roller coaxially installed on the crushing barrel, the crushing roller is sleeved with multiple crushing paddles, and a coal outlet hole is formed in the crushing net. The coal-fired boiler convenient to improve the coal combustion efficiency is used for the coal-fired boiler.

Description

technical field [0001] The invention relates to a coal-fired boiler, in particular to a coal-fired boiler which facilitates the improvement of coal combustion efficiency. Background technique [0002] With the continuous innovation in the field of coal-fired boilers in recent years, in view of the problems existing in the use of existing coal-fired boilers, they are constantly optimizing in terms of energy saving, emission reduction, and energy consumption reduction. Especially how to improve the combustion efficiency of coal, and the combustion in the furnace is an integral process of pulverized coal oxidation and heat generation. We can divide it into two aspects: one is the air-to-coal ratio in the furnace, the ratio of primary and secondary air, and the burner The combustion conditions formed by the working conditions, one is the influence from the tertiary wind and the outside world (mainly negative pressure, air leakage, etc.), that is, the disturbance of the tertiary ...
