Abstract

The invention discloses a pulverized coal additive device special for thermal power generation equipment. The main structure of the pulverized coal additive device special for the thermal power generation equipment comprises a thermal power generation furnace, a sulphur container, a nitric acid container, a hydrogen container, an air compressor, a mixing pipeline, adjustment valves and a spraying nozzle, wherein the spraying nozzle is installed on the lower portion of the thermal power generation furnace and connected with the mixing pipeline; the sulphur container, the nitric acid container and the hydrogen container are sequentially installed on the upper portion of the mixing pipeline from left to right; the adjustment valves are installed between the sulphur container and the mixing pipeline, between the nitric acid container and the mixing pipeline as well as between the hydrogen container and the mixing pipeline and can adjust the proportion of three kinds of additives. The three kinds of additives of sulphur powder, nitric acid and hydrogen are blown into the thermal power generation furnace according to a certain proportion through ultra-high pressure compressed air, so that fuel in the thermal power generation furnace is combusted more thoroughly, emission obtained after combustion has no pollution, the utilization rate of the fuel is increased, the purposes of saving energy and protecting the environment are realized, and the pulverized coal additive device special for the thermal power generation equipment has broad market prospects.

Description

technical field [0001] The invention relates to an auxiliary device for power generation, in particular to a pulverized coal additive device dedicated to thermal power generation equipment. Background technique [0002] With the development of economy and society, industrial power consumption increases rapidly. In order to improve efficiency, power plants pay more and more attention to fuel utilization and energy saving and emission reduction. However, due to structural reasons, the coal-fired power equipment of most domestic power plants has problems such as poor energy saving and emission reduction effects, low fuel utilization rate, and high maintenance costs, which seriously affect the development of power plants. Contents of the invention [0003] Aiming at the problems existing in the coal-fired power equipment of the existing power plant, the present invention proposes a special coal powder additive device for thermal power equipment, which uses high-pressure compre...
