From the soot blower header, high velocity steam jets are blown through the soot blowers to clear soot accumulated in the boiler. When soot blowers open and close suddenly, the possible pressure surges in the header line is controlled by the header control valve. MIL 41000/71000/91000 control valves are successfully employed for the applications in Thermal power plants. The body shall be Get Price
Sonic soot blowers are a proven alternative to conventional steam soot blowers in power generation plants which burn a range of fossil fuels and other waste fuels including biofuels. Depending on the application and boiler plant design, sonic soot blowers usually totally replace existing high maintenance steam soot blowers whether of the retractable or rotary type.Get Price

A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency. Types of soot blowers: Wall Blowers also known as IRs (InsertableGet Price
Soot blowers are used for removing soot build-up from boiler tubes typically associated with fossil fuel burning and power generation. John Crane offers soot blower sets for most soot blower models. These sets consist of chevron-style middle rings to accommodate both the rotational and reciprocating motion of the soot blower lance tubes, and male and female end rings that conform to the Get Price
Soot deposition has a thermal conductivity of only 0.0581-0.116w/m2*, while boiler tubes have 46.5-58.1w/m2* . Soot accumulated on the heating surface of heat exchanger (evaporator, superheater, economizer, air preheater) would cause lower heat conduction, higher exhaust gas temperature, more heat loss, lower steam generation.Get Price
10/2/2011 · The soot-blower nozzles are located at strategic positions in the flue-gas passages and the frequency of use depends on the extent and nature of the deposits. As a general guide, a complete sequence of soot blowing may be carried out once per 8-hour shift with a varying duration of blow-time. Single high-pressure steam nozzles are ( Figure 24 Get Price
