Description

A multi-directional collection and sampling device for boiler flue gas

technical field

The utility model relates to a boiler multi-directional collection flue gas sampling device, which belongs to the technical field of flue gas collection and processing.

Background technique

In the performance test of power plant boilers, the calculation of boiler thermal efficiency and air leakage of air preheater is inseparable from the measurement and analysis of flue gas components. The flue gas composition at the inlet and outlet of the air preheater can calculate the air leakage rate of the air preheater, and can judge the combustion conditions of the boiler. The flue gas composition at the outlet of the air preheater can calculate the thermal efficiency of the boiler; in today's my country, environmental protection Under the background of increasingly stringent requirements, flue gas composition measurement can conduct qualitative or quantitative analysis of the pollutant composition in boiler flue gas, so as to effectively optimize the combustion of boilers, so as to achieve the goals of optimized operation, energy saving and emission reduction.

The size of the flue ducts of modern large-scale power plant boilers is relatively large, and the flue gas distribution is uneven on the cross-section of the flowing flue gas. Therefore, the grid method is often used for flue gas sampling. For the measurement of flue gas composition of power plant boilers, a single thin iron pipe is often used, with only two ends open, one end inserted into the flue, and the other end connected to the flue gas analyzer. During the measurement, the sampling pipe is gradually pulled out according to a certain length, Measure a set of data at each point to achieve the goal of the entire section grid method. This method takes a long time to measure the pipeline, has a large workload, and has a large manual error. During the test, the sampling pipe is divided into points according to a certain length during the measurement as time changes. When pulling out gradually, the combustion state of the boiler is also changing, thus the real grid method sampling test cannot be achieved, and the measurement accuracy is low.
