Abstract

This invention discloses a controlling system of fossil oil serum coke which is used to control the burning device so as to make the fossil oil serum coke to burn efficiently. This burning-control system adopts the burning space heat sensor and the baroceptor to sense the temperature and gas pressure. It also compares the sensing data with the corresponding parameter data stored in the program controller and automatically makes sure the adjusting proposal according to the result. The program controller is used to control the serum and air intake amount of the serum pump so as to keep the temperature of the burning space between the burning point and coking point and make the burning space steady sub-pressure so as to make the fossil oil serum burn efficiently and avoid coking or flame out.

Description

technical field [0001] The invention relates to boiler equipment, more specifically, the invention relates to a combustion control system using petroleum coke slurry as fuel. Background technique [0002] On the one hand, with the increasing environmental pollution, boiler equipment has basically switched to clean energy, such as oil, natural gas or coal gas, but this has greatly increased the fuel cost of boiler equipment. On the other hand, the energy crisis has become a worldwide concern. The natural energy that can be used by human beings is getting less and less, but the human demand for natural energy is increasing. Therefore, all countries in the world are adjusting their energy structure to save the existing energy to the greatest extent. [0003] People are constantly looking for new clean energy. The use of low-cost, high-efficiency and clean petroleum coke slurry fuel can not only make reasonable use of natural resources, but also reduce the fuel cost of boiler...
