Long Retractable Sootblower utilizing steam as a cleaning medium. 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. The world market leader is Clyde Bergemann Power Group. [citation needed]

Although it is possible to extend the sootblower’s service life, boiler operators need to follow maintenance best practices to ensure safety, reliability, and at the same time, control the maintenance cost.

Each soot blower, whether selected manually or automatically, carries the spray assembly in an advance-and-retract mechanism to clean a region of the tube walls around it by blowing a steam jet at very high velocity. The blowing medium for soot blowers may be anything such as steam, water, or compressed air.

The more common and reliable cleaning method for selective catalytic reduction (SCR) system catalyst is by sootblowing with steam or air. Catalyst blocks have also been cleaned by acoustic devices where site-specific conditions allow.

Emerson's Ovation soot blower optimization system delivers adaptive sequenced sootblowing control that efficiently manages cleaning media use while avoiding opacity levels, targeting ideal temperatures, and time aspects.

Sootblowing is an often-neglected aspect of the operation of a pulverized coal boiler, yet the way sootblowers are used can have a significant impact on the financial bottom line. Recent studies performed by the Energy Research Center show how optimizing sootblowing practice can help reduce emissions and improve unit heat rate.

2004年4月18日 · Sootblowing is used to control the level of ash and slag deposits on the boiler heat transfer sections. On-line cleaning of localized areas is performed by sootblowers using high...

2015年1月28日 · Sootblowing is a classical optimization problem: the effect of better heat transfer is counter balanced by the costs of the consumed utilities. Increased sootblowing frequency and cleaning cycles have a negative impact on the operating costs. The main optimization problem is the determination of the optimum time frequency of cleaning cycles.

2014年11月1日 · Typical sootblower equipment uses jets of steam, water, or air to remove deposits on heating surface tubes. Sootblowing increases power generation costs, both from expenses associated with the...

Sootblowing is used to control the level of ash and slag deposits on the boiler heat transfer sections. For best boiler performance it is important to maintain an optimal balance between...
