How much is a 3.5MW gas heated water boiler
The 3.5MW gas-fired heating water boiler is actually a 5-ton hot water boiler. The gas-fired heating water boiler is divided into “dry-backed” and “wet-backed”.
Although dry type production process is relatively simple, and don’t need too much material, but as a result of the furnace outlet flue gas temperature is higher, high temperature flue gas counter rotating smoke chamber of direct radiation refractory erosion, often appear to burn fracture, field, lead to short circuit, two, three, return flue gas overheat the boiler tail, serious to burn the red back cover, it is also dry back structure caused by large boiler shortcomings.
After wet back boiler furnace, furnace back into the combustion chamber is the “wet” of bubble in the water back into the combustion chamber, which is the great difference between dry type and wet type back back, wet type furnace, back to back absorption into the combustion chamber heat transfer water directly, avoids the problem of burning, but also improves the 3.5 MW the radiation heat transfer area of gas heating hot water boiler and heat transfer efficiency, this kind of structure is widely used in the world.
