Company introduction

Henan KWB Machinery Manufacture Co., Ltd cooperates with Machinery Research Institute of Henan Province. We devote to development and manufacturing of boiler cleaning equipment and pneumatic conveying equipment. Also, Good unites with famous companies like East Boiler, Haerbin Boiler, Kaifeng Desheng Boiler to provide solid foundation and strong technical support for the promotion of intelligent impulse shock wave sootblower. shock wave sootblower is widely used for coal-fired, oil-fired, waste incineration boilers soot cleaning in oil, chemical, coal chemical, thermal power, cement, environment protection industries.



shock wave sootblower introduction



During the operation of industrial boilers, fouling and coking on the surface of convection section is normal. Soot deposition has a thermal conductivity of only 0.***1～0.**6w/㎡·°C, while metal tube has *6.5～*8.1 w/㎡·°C. Soot on tubes would result in a higher exhaust gas temperature, lower boiler thermal efficiency, tubes erosion & leaking, sometimes, even a forced blowing out. Boiler cleaning equipment is required.



Pressure pulse soot blower is the newest type of boiler cleaning equipment. As a substitute product of long retractable soot blower (steam), short soot blower (steam), sonic soot blower, shock wave sootblower is a major breakthrough for boiler tube cleaning.



It uses the detonation impulse technology to clean the convection section of boilers, such as superheater, reheater, economizer.



After the application for various boilers, impulse dry cleaning method has replaced traditional steam wet cleaning method. shock wave sootblower has solved the problems caused by steam soot blower and sonic soot blower. Steam blowing increases the humidity, which is potential damage for the tubes. Sonic blowing has a relatively lower energy and not efficient for different types of deposits.



shock wave sootblower improves the cleaning efficiency greatly, reduces tube erosion rate, lowers maintenance, improves thermal efficiency, reduces operation cost.



Working principle and features



Combustion gas (coal gas, natural gas, ethyne, liquefied gas, etc.) is mixed with air to some percentage. On the base of turbulent flow status and adjustable impulse frequency, mixed gas detonation would generate powerful wave airflow, together with shock wave and thermal radiation. shock wave sootblower uses the kinetic energy, sound energy and thermal energy to clean boiler.



For different boilers, soot fouling is different. According to different situation, the ratio of combustion gas and air varies. Therefore, generated pressure would be different. But it is limited within safety range, instant energy at the nozzle is about 0.6MPa.
