Horizontal pulverized coal organic heat carrier boiler

Abstract

The invention relates to the field of boilers, in particular to a horizontal pulverized coal organic heat carrier boiler. The horizontal pulverized coal organic heat carrier boiler comprises a boiler body, a base and at least one combustor. A burnout chamber composed of a radiation segment coiler and a roof tube and provided with a downward opening is arranged in the boiler body. The lower portion of the boiler body is fixedly connected with the base. At least one temperature sensor is arranged in a hearth and a combustor interface is arranged in one side of a combustion chamber. The upper portion of the side, opposite to the combustor interface, of the burnout chamber is provided with a smoke outlet. The combustor is arranged at the combustor interface and communicated with the hearth. An ignition device is arranged on the combustor. According to the horizontal pulverized coal organic heat carrier boiler, the temperature sensor is arranged in the hearth and used for feeding the temperature in the hearth back at any time, so that the fire power of the combustor can be regulated in time according to the temperature variation in the hearth and the temperature of soot particles in the smoke is controlled to be lower than the ash fusion point before the soot particles are in contact with a wall face of the hearth and a wall face of a heated pipeline. The probability of coking of the wall face of the hearth and the wall face of the heated pipeline is reduced.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a horizontal pulverized coal organic heat carrier boiler. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . [0003] The main working principle of the boiler is: use the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water or organic heat carrier in the container, so that the water or organic heat carrier can reach the required temperature or steam at a certain pressure. [0004] According to the types of fuel used in boilers, they are classified into coal-fired boilers, oil-fired boilers, gas-fired boilers, and pulverized coal boilers. [0005...

AI Technical Summary

Problems solved by technology

[0006] In the existing pulverized coal boiler, the combustion control is not good, the combustion efficiency is low, and the temperature in the furnace cannot be well controlled. The furnace temperature is too high, and the ash particles in the flue gas contact the boiler furnace and heating surface pipes. On the wall, the boiler furnace and the wall of the heating surface pipe are easy to coke after cooling
