A coal tar combustion device

Abstract

The invention discloses a coal tar combustion device which comprises an oil tank, a preheater, a first oil filter, a second oil filter, an oil pump, an oil return pipe and a combustor. The preheater and the first oil filter are arranged in the oil tank; a thermometer is mounted on the oil tank; the first oil filter is connected with the oil pump through a ball valve and the second oil filter; the oil tank is connected with the oil pump through the oil return pipe, a one-way valve and an overflow valve; the oil pump is connected with the combustor through pipelines and a flow control valve; a pressure gage is mounted at one side of the oil pump; the combustor can be connected with a combustion chamber through a combustor nozzle and connected with the oil return pipe through a pipeline; and the combustion device further comprises a temperature control system which can control a combustor pulse valve to be opened and closed according to the temperature of the combustion chamber. According to the coal tar combustion device, coal tar is heated and softened through the preheater and purified through double-stage filtration, blockage of the combustor nozzle and the pipelines is prevented, and the combustion efficiency of the coal tar is improved.

Description

Technical field: [0001] The invention relates to a combustion device, in particular to a coal tar combustion device. technical background: [0002] Coal tar, also known as coal paste, coal distillate, and coal tar solution, is a black or dark brown viscous liquid with a specific gravity greater than water. It has certain solubility and a special odor. It is flammable and corrosive. [0003] Compared with coal, coal tar burns cleanly and has a high calorific value; compared with natural gas, coal tar is safe, easy to store and not subject to geographical restrictions; compared with light oil, coal tar is economical and cheap. In recent years, people have gradually used coal tar as an alternative fuel, but coal tar has high viscosity, poor atomization performance, poor combustion performance and pollutes the environment when it is directly burned. Therefore, it is necessary to design a device to improve the combustion performance of coal tar. [0004] The announcement number...

Problems solved by technology

[0004] The announcement number authorized by the 2003 announcement is CN2553248Y, and the name is a combustion device for heavy fuel oil. Although this device solves the problem of heavy oil viscosity, it often affects the combustion efficiency due to poor atomization, and it is easy to block the oil delivery and combustion pipes. road problem, but the combustion device is suitable for medium-viscosity fuel oil, and the viscosity of coal tar is high, the combustion device is not suitable for coal tar combustion
