Combustion chamber combustion temperature measuring system based on laser radar

Abstract

The invention discloses a combustion chamber combustion temperature measuring system based on a laser radar. The system comprises a furnace body, a first installation plate, a second installation plate and fixing inserting rods, clamping grooves which fit the fixing inserting rods are formed in the two sides of the inner walls of the furnace body, pressing grooves are formed in the tops and bottoms of the inner walls of the clamping grooves, T-shaped pressing heads are fixedly connected with the inner walls of the pressing grooves through pressing springs, and a laser emitting device is fixedly connected with the side of the first installation plate. The invention relates to the technical field of gas temperature measuring facilities. By means of the system, gas temperature in a combustionchamber can be timely obtained by using a TDL analysis system, so that the monitoring accuracy is greatly improved through the analysis of absorbing ray relative strength, observation can be extremely conveniently performed by workers, the clear and accurate displaying of monitoring data values of gases in a furnace cavity can be achieved, and the purposes of improving production efficiency and preventing the heating of excess air are achieved.

Description

technical field [0001] The invention relates to the technical field of gas temperature measurement facilities, in particular to a laser radar-based furnace combustion temperature measurement system. Background technique [0002] Coal remains one of the most important energy sources in the world, accounting for about 27% of energy supply, and the average efficiency of coal-fired power plants in converting coal's energy into electricity is about 30%, so there is huge room for improvement in optimizing combustion , in order to minimize the impact on the environment, the flue gas treatment adopts a treatment method similar to that of waste incineration plants. In actual combustion, due to insufficient mixing of fuel and oxygen, excess oxygen (air) must be provided. Excessive oxygen content will be caused by cold Increased NOx levels due to air dilution, energy loss, low oxygen levels increase carbon monoxide formation, therefore, sufficient air is an important parameter for an o...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a furnace combustion temperature measurement system based on laser radar, which solves the problem that the existing monitoring method has low monitoring accuracy and is very inconvenient for staff to observe, and cannot realize clear and accurate furnace chamber temperature measurement. The monitoring data value of the internal gas is displayed, which cannot improve the production efficiency and avoid the problem of heating the excess air.
