Sootblower __hot__ -
Let’s break down what they do, why they fail, and how to get the most out of them. Before we talk about the solution, let’s quantify the problem. A soot layer just 1/16 of an inch thick can reduce boiler efficiency by 2-3%. That might not sound like much, but on a 500 MW boiler, that translates to millions of dollars in excess fuel annually.
Most sootblowers fall into two categories: These are the giants of the boiler. They feature a long lance that travels into the boiler flue gas path, rotates, and blows cleaning media through nozzles. They are used in high-temperature zones (superheaters, reheaters, economizers). sootblower
The lance travels in, begins rotating, blows steam, then retracts. The entire cycle takes 2–5 minutes. 2. Fixed-Position (Wall Blowers) These are shorter, permanent fixtures that blow a fixed jet into the furnace walls. They do not travel. They are typically used in the furnace itself to prevent slag buildup on membrane walls. Let’s break down what they do, why they
