Industry Gas Fired Steam Boiler Natural Gas Hot Water Boiler Quick Steam Generation

Our 3 pass gas fired steam boiler adopts unique large combustion chamber design, three-way wet back structure, which can keep low temperature combustion, improve boiler efficiency and reduce NOX emissions.

What is the 3 pass gas fired steam boiler structure of a steam boiler?

1. The 3 pass gas fired steam boiler structure of a steam boiler means that the fuel is burned in a micro-positive pressure in the furnace, and the high-temperature flue gas flows back into the first flue pipe bundle through the return chamber along the furnace.
2. The compressed front box turns 180° into the second tube bundle.
3. After convective heat transfer, discharge into the atmosphere.
We use the design of the center-symmetric three-return structure to design a large capacity, steam foot, and get the customer's favorite.

What is the principle of the 3 pass gas fired steam boiler design of a steam boiler?

The 3 pass gas fired steam boiler design mainly considers the principle of boiler overhaul and stability. The water mixing device installed in the backwater inlet of the boiler first flushes the pipe bundle of the pipe and then contacts the furnace to improve the water temperature of the returning water contacting the furnace. Avoid local overcooling and boiling.

The furnace water is in the lower layer of the high temperature flue gas, and the low temperature flows in the upper part. Thermal convection reaches the maximum heated structure. The gas steam boiler also reaches a large vaporization space, and the partition is added to the rear part to cause the circulating water to flow back to the high temperature surface of the combustion chamber, and the reasonably uniform heat conduction ensures the safe operation of the tube plate of the back combustion chamber.
