A soot blowing system retrofit for a 530 tDS/d recovery boiler, involving 17 SW-SLRM long retractable soot blowers, dual positive-pressure cleaning wall boxes, sealing-air upgrades and improved steam pressure control to address alkali deposits, lance jamming and aging equipment.
Soot blower performance depends on more than steam pressure. Nozzle diameter, jet direction, blowing distance, medium flow and soot blower movement all affect cleaning coverage and intensity. This article explains why nozzle design must be matched to the boiler heating surface and deposit conditions.
Long retractable soot blowers are widely used to clean superheater, reheater and economizer tube banks in industrial boilers. This guide explains how they work, why the lance both travels and rotates, and which engineering parameters must be considered during selection.
A steam soot blowing system retrofit for a waste-to-energy boiler using 9 SW-SLRM long retractable soot blowers across the third-pass superheater and economizer sections, with positive-pressure sealing, protective air, steam piping and DCS-integrated control.
A soot blower is an online boiler cleaning device used to remove ash and slag deposits from heating surfaces. This guide explains how different soot blower types work, where they are installed, and how engineers select the right cleaning method for different boiler zones.
SCR systems are critical for NOx reduction but are highly vulnerable to ash plugging and ammonium bisulfate formation. Learn how specialized rake sootblowers and sonic cleaning technologies can protect your catalyst and ensure emission compliance.
A large-scale steam soot blowing system retrofit for three industrial boilers in northern China, involving 108 furnace soot blowers, 42 long retractable soot blowers, and comprehensive optimization of steam piping, drainage, boiler interfaces, control systems, installation, and commissioning.
A complete soot blowing system retrofit for two paper mill boilers using 40 SW-SHRS semi-retractable soot blowers, with temperature-specific lance materials, steam pressure reduction, drainage optimization, DCS integration, installation and commissioning.
Biomass and Waste-to-Energy (WtE) boilers face severe slagging and sticky ash issues due to high alkali content in fuels. Discover how specialized sootblowing strategies can prevent tube corrosion, maximize heat transfer, and avoid unplanned shutdowns.
High exhaust gas temperatures waste energy and reduce boiler efficiency. Discover how upgrading traditional sootblowers to Sheenway's advanced solutions can effectively reduce thermal resistance, optimize heat transfer, and lower coal consumption in coal-fired power plants.
