The two most common types of boilers are fluidized bed boilers and pulverized coal-fired boilers. In this section, we will explore common issues arising in this equipment, and how IGS can solve them. We offer services for CFB, Pulverized coal, FGD (Flue Gas Desulfurization) Units, Economizers, Soot blowers, and SCR (Selective Catalytic Reactors).

Wall Blowers Optimization in Boile

2019-2-4 · In a large boiler of around 1500t/hr capacity, the total number of soot blowers can be around 120. In this, around 90 numbers will be wall blowers. The frequency of soot blowing will depend on the type of coal being fired. However the operating group must remember that the initial suggested sequence and frequency is more general and has to be

The patented HISS technology, originally developed by the company SootTech, transforms your steam sootblowing system into an effective tool that handles clogging and increases the efficiency of your power and recovery boilers. • Halve your steam consumption • Increase you production of electricity • Double your sootblowing power • Use cheaper fuel Works on allContinue reading →

Rotary Soot Blowers in Boilers for Thermal Power Plan

A large coal fired Thermal power plant will have around two hundred soot blowers of both types arranged to cover all the area of the boiler. This will be programmed to automatically operate to a required sequence. Intelligent soot blower systems calculate the trends in the temperature increase in different sections of a boiler.
