Chemical cleaning of industrial boilers is a common method that effectively removes dirt and deposits inside the boiler, enhancing heat exchange efficiency and extending the boiler's lifespan. Below are the general steps and methods for industrial boiler chemical cleaning: Preparation: Turn off the boiler's power and gas supply, drain the water and steam from the boiler, and ensure the boiler is in a safe condition. Prepare the required chemical cleaning agents and cleaning equipment. Cleaning Agent Selection: Choose a suitable chemical cleaning agent based on the boiler's material and the nature of the dirt. Common cleaning agents include acidic cleaners, alkaline cleaners, and chelating agents. Cleaning Agent Circulation: Dissolve the cleaning agent in an appropriate amount of water and circulate it into the boiler through a pump. Determine the circulation time and temperature of the cleaning agent based on the size of the boiler and the extent of the dirt. Cleaning Agent Action: During circulation, the cleaning agent reacts chemically with the dirt inside the boiler, dissolving and decomposing it. Acidic cleaners can remove rust and scale, while alkaline cleaners can remove grease and organic matter. Rinsing and Neutralizing: After the cleaning agent circulation is complete, rinse the boiler with clean water to flush out the cleaning agent and dissolved dirt. At the same time, use a neutralizer to neutralize any remaining acidic or alkaline substances, ensuring the boiler's neutrality. Inspection and Maintenance: After cleaning, inspect the boiler to ensure the cleaning effect and normal operation. Perform necessary maintenance and upkeep as required. Points to note when conducting industrial boiler chemical cleaning: - Adhere strictly to the instructions for use and safety operating procedures for chemical cleaning agents to ensure the safety of operators. - Choose the appropriate cleaning agent and method based on the boiler's material and the properties of the cleaning agent. - Control the concentration, temperature, and circulation time of the cleaning agent to avoid unnecessary damage to the boiler. - Monitor the concentration and pH of the cleaning agent in a timely manner during the cleaning process and adjust the cleaning conditions. - Flush the boiler after cleaning to ensure that all cleaning agents and dirt are completely removed. - Perform boiler maintenance and upkeep promptly after cleaning to ensure normal operation and long-term use.

When a gas steam boiler experiences overpressure, the following immediate measures must be taken: 1. Shut off the gas supply: First, immediately close the gas supply to cut off the fuel source and stop the combustion process to prevent further increase in steam pressure. 2. Open the pressure relief device: Open the boiler's pressure relief device, typically a safety valve. The safety valve is a crucial safety feature of the boiler that automatically opens when the internal pressure exceeds the set value, releasing overpressure steam to lower the boiler pressure. 3. Reduce the burner load: If the overpressure is due to excessive burner load, reduce the burner load to decrease steam production and thereby lower the boiler pressure. This can be achieved by adjusting the gas supply to the burner or modifying the burner's control method to match the current load requirements. 4. Inspection and maintenance: After an overpressure event, the boiler should be inspected and maintained to identify the cause of the overpressure and make repairs. Possible causes include burner malfunctions, control system failures, and valve malfunctions. If necessary, a boiler maintenance technician should be called in for inspection and maintenance. It is important to note that overpressure is a dangerous condition in boiler operation and must be addressed promptly. When dealing with overpressure, operators should remain calm, follow safety operating procedures, and ensure their own safety. If unsure how to handle an overpressure situation, immediately contact a boiler maintenance technician or relevant technical support personnel for assistance.
