AI Technical Summary
Existing gas-water heat exchangers are prone to dust accumulation on the heat exchange tubes, leading to blockages and affecting gas flow.
A soot blowing tube assembly is installed in the gas-water heat exchanger. High-pressure gas is introduced through the air inlet pipe, and the heat exchange tubes are blown with evenly arranged air holes to prevent dust accumulation and caking.
It effectively prevents heat exchange tube blockage, maintains normal gas flow, increases flow area, enhances blowing intensity and operating range, reduces gas loss, and achieves all-round and efficient ash removal.
