Sufficient-combustion boiler with grinding function for power generation

Abstract

The invention relates to a sufficient-combustion boiler with a grinding function for power generation. The boiler comprises a hearth and a water tank, and further comprises a grinding mechanism and aventilation mechanism, wherein the grinding mechanism comprises a feeding box, a feeding pipe, an inlet pipe, a filter screen, a lifting assembly, a moving plate and two crushing assemblies, the crushing assemblies comprise transmission units, crushing plates, limiting units, rotating shafts and first bearings, and the ventilation mechanism comprises an air cylinder, a piston, a connecting rod, anair inlet pipe and an air outlet pipe. The sufficient-combustion boiler with the grinding function for the power generation conducts crushing work on coal briquettes through the grinding mechanism intwo modes, the crushing effect is improved, the situation that the coal briquettes are large and cannot be sufficiently combusted is avoided, the utilization rate of the coal briquettes is increased,the function of ventilating the hearth is achieved through the ventilation mechanism, the oxygen content of the interior of the hearth is increased, and pulverized coal is sufficiently combusted.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a fully combusted boiler with a grinding function for power generation. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, whi...

AI Technical Summary

Problems solved by technology

[0003] Existing boilers directly use coal blocks for combustion, resulting in partial coal blocks being unable to be fully burned, thereby reducing the utilization rate of coal materials and wasting energy. Not only that, the existing boilers have low oxygen content in the furnace , it is prone to the phenomenon that the coal is not fully burned, which greatly reduces the practicability of the existing boiler
