The commercial low nitrogen condensing hot water boiler is a pre mixed condensing low nitrogen commercial hot water boiler designed and produced by a four-way boiler. It uses two new technologies, condensation heat exchange technology and pre mixed combustion technology.

The core component of the fully premixed low nitrogen condensing gas boiler, the main heat exchanger, is made of silicon aluminum and integrates the combustion chamber, flue, and waterway. The cast aluminum heat exchanger has good corrosion resistance, and within a limited volume, the column shaped heat absorbing column has a large heat transfer area. The combustion chamber and outlet are located above the main heat exchanger, and the inlet is located at the bottom. The temperature of the water flow gradually increases from bottom to top, while the temperature of the flue gas gradually decreases from top to bottom. The reverse flow ensures that every point in the heat exchanger can perform sufficient heat exchange, absorb sensible heat and most of the latent heat of water vapor in the flue gas, and reduce the exhaust temperature to a limited extent, so that the water vapor in the flue gas saturates and precipitates, achieving the goal of true efficiency, energy saving, and environmental protection.

Pre mixing technology refers to the pre mixing of gas and air before the fan, and the pre mixed air enters the combustion chamber through the fan. Gas servo proportional valve and automatic premixed control technology enable gas to be fully mixed with air in proportion before combustion. By adjusting the gas proportional valve, high-efficiency and low emission combustion of gas can be achieved. Using a metal fiber burner to evenly burn the premixed gas on its surface. Avoiding local high temperatures, reducing nitrogen oxide emissions, and achieving radiative heat transfer.

Commercial low nitrogen condensing hot water boilers are widely used for heating, bathing, and domestic hot water in enterprises and institutions such as hotels, schools, guesthouses, residential areas, office buildings, factories, etc.
