Combustion burner for condensing gas hot water boilers

The burner of a condensing gas water heater is one of the core components of the boiler. If it malfunctions, the boiler will fail to operate normally. Common burner issues include the motor not rotating, failure to ignite, flame extinguishing within 5 seconds after ignition, shutdown with the air damper in a controlled state, and the burner motor not rotating. Troubleshooting the cause of the malfunction and performing repairs can resolve these issues. To minimize burner failures, it is essential to focus on its maintenance and upkeep, covering three main aspects: the main gas supply, the regulating valve, and the burner itself. Below, let’s explore the common faults of condensing gas boiler burners.

Common Burner Faults and Solutions

The burner of a condensing gas water heater is a critical component of the gas boiler, consisting of five main parts: the air supply system, ignition system, monitoring system, fuel system, and electronic control system. It is responsible for gas combustion, providing the heat source for the boiler. As a highly automated electromechanical device, the condensing gas water heater burner may encounter some faults during operation, which require timely maintenance and resolution.
