Product application background

At present, some boilers have found that the heating surface of the boiler has contamination and coking in the process of mixing coal, and a large number of unmelted ash particles are attached to the wall of the screen, high, high, low, and low. According to the characteristics of coal, some power plants reduce and alleviate the contamination and coking of boilers by implementing coal-fired blending, soot blowing on the heating surface of the boiler, and spraying nanomaterials on the heating surface of the furnace during the normal production and operation of some power plants. Because the specific situation inside the boiler is not clear and understandable, to understand the contamination and coking of the heating surface tube inside the boiler, the general location and the degree of contamination and coking can be comprehensively judged by the changes in the parameters of the flue gas and soda-water system. During operation, open the manhole doors of the boiler to observe for verification. Judging the contamination and coking conditions of the heating surface tubes through the changes of the parameters of the flue gas and soda-water system requires higher operating experience for the operators; during operation, opening the manhole doors of the boiler to observe the contamination and coking conditions of the heating surface tubes has certain dangers sex. Long-term high-frequency soot blowing will damage the boiler tubes to a certain extent and bring safety hazards to the operation of the boiler unit. Using a special method, the coking and contamination of each heating surface in the furnace can be checked by a special boiler coking detector, and the coking and contamination of the furnace and each heating surface can be accurately judged, so that effective measures can be taken to control the coking of each heating surface. , contamination, and at the same time can achieve precise soot blowing, reducing the probability of pipe burst due to soot blower damage to the pipeline.

Solutions

The Boiler coking observation instrument Inspection System is a revolutionary system that uses high-performance multispectral technology and images are processed by special algorithms for dust filtering. The unique high temperature resistant design allows the detector to be used online without shutting down the boiler to observe the coking condition of the boiler water wall and superheater. The system allows coal-fired power plants to operate more efficiently, extract more energy from coal and increase productivity. The observable installation positions are: burner, superheater, economizer, out-of-stock position, etc. With the BID-800 system, coal-fired power plant operators can proactively manage their boilers by visually viewing the scale of boiler tubes. This results in significantly fewer cleaning cycles and downtime, resulting in improved operational efficiency and reduced mechanical stress that can lead to boiler tube failure.

Product introduction

The  Boiler coking observation instrument adopts air cooling, and the detector can be directly inserted into the boiler for observation when the boiler is running.
