Because of its reasonable structure design and excellent performance, the development prospect of oil – fired water tube boiler is very good. Water tube boiler price set reasonable, boiler can meet the demand of different evaporation.” D “type boiler, reasonable design, mainly by the upper drum, lower drum, header, water wall, convection tube bundle, furnace and burner and other parts. Therefore, in addition to the furnace and burner, other components are subjected to the saturation pressure of the boiler.
The furnace of this series boiler is mainly a place for fuel atomization and combustion. Its role is to provide enough space so that its fuel can be fully burned. At the same time, the heat from the combustion is not lost to the outside of the boiler. Furnace is composed of refractory brick wall and water-cooled wall. The water-cooled wall can absorb the radiant heat of high temperature flame and flue gas, so it can be white firebrick, which has the function of cooling furnace wall. At the same time, it can also improve the evaporation rate of the boiler.
Water tube boiler price is competitive, after fuel atomization combustion, high temperature flame and flue gas and furnace water wall, heating surface and slag tube for strong radiation heat exchange. The flue gas is then directed to the convective heat transfer flue. Before entering the superheater, the fumes need to pass through three rows of slag traps to properly cool down. The superheater can be protected from the direct irradiation of the high temperature flame in the furnace. This series of boiler products in the body heating surface layout, can be very convenient to increase or decrease the size and quantity, easy to form different evaporation capacity of the boiler.
Because this series of products have mastered the application technology of water wall, for the boiler with different evaporation capacity, under the condition of different furnace volume heat load, the heating area of water wall can be increased or decreased to control the flue gas temperature at the outlet of the furnace. So that the furnace has a certain temperature level. Both can ensure good combustion, and can protect the furnace wall. And at the exit of the furnace, there will be no bad phenomena such as coking and corrosion of convection tube bundle caused by the use of inferior fuel.
Each boiler will have a critical load given the steam pressure, drum size and salt content of the boiler water. When the load is less than the critical load, the amount of water in the steam belt will increase slightly with the increase of the load. When the load exceeds the critical load, the amount of water in the steam belt increases sharply. When the evaporation of the boiler increases, if the volume of the boiler is reduced, the furnace volume heat load must be appropriately increased to reduce the volume and weight of the boiler per unit evaporation.
Water tube boiler price is reasonable, boiler internal are bent water pipe, tube cross section is smaller than the tube outside, water flow rate greatly increased. At the same time, it also has extremely fast water flow rate and excellent water circulation system, high evaporation efficiency, strong performance to adapt to load changes, more suitable for high working pressure environment, boiler heat absorption rate and high thermal efficiency.
