What is the first step when using a soot blower?

Opening the steam line drain is indeed the correct first step when using a soot blower. This action is essential because it ensures that any condensed water or impurities in the steam line are removed before the soot blower is activated. If the steam line is not drained, it can lead to mixed condensate and steam, which might impede the efficiency of the soot blower and potentially damage the system or lead to inadequate cleaning of the boiler surfaces. Proper drainage helps maintain optimal performance during the soot removal process.

While checking pressure levels, inspecting the soot blower, and activating the soot blower are important steps in the overall procedure, they should only occur after ensuring that the steam line is free from any obstructions or unwanted condensate. Each step must be properly sequenced to ensure safety and operational efficiency.
