Introduction of WNS Series Gas Fired Firetube Boiler

The WNS series gas fire tube boiler is a horizontal, shell-type, wet-back, three-pass smoke tube boiler. Gas is introduced into the boiler burner through pipelines and mixed with air to form a combustible gas mixture. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere. The tail of the flue is equipped with an economizer and a condenser, which can achieve low emissions of harmful gases and high energy utilization.

Features of WNS Series Gas Fired Firetube Boiler

High Efficiency: The WNS series boiler adopts a wet-back structure and a three-pass or two-pass fire tube design. It is equipped with advanced burners, an economizer, and a condenser at the tail of the flue, achieving a thermal efficiency of over 98%. Additionally, the threaded smoke tubes enhance the heat transfer coefficient of the boiler.

Environmental Friendliness and Energy Saving: The low-nitrogen combustion technology effectively suppresses the emission of NOx, reducing environmental pollution.

Safety and Reliability: The WNS series boiler is equipped with multiple protection systems, including high and low water level alarms, extremely low water level protection, overpressure protection, and flameout protection. These functions ensure the safe and reliable operation of the boiler.

Easy Operation: The design of this series of products is rational, installation is convenient, and the level of automation in operation is high, making it simple to operate.
