The product for double drum longitudinal type "D" type is decorated in bulk water tube boiler. It is composed of the water drum, membrane type water wall, superheater, convection bank and economizer, burner arrangement in the front wall, after fuel burning in the hearth, flue gas heat exchanger, convection bank, economizer, into the chimney.

The boiler automatic control functions to satisfy the rules of the boiler technology * * (2012), to the requirement of gas boiler is equipped with perfect automatic control device and * * protection devices, realize the water level automatic control and dangerous low water level alarm, and the furnace; Steam pressure, overpressure automatic control and overtemperature alarm; The overpressure interlock protection device, low water level interlock protection device. Ensure the boiler running * *. And hold * * ignition process control and flame-out protection device. And interlocking device has the following features:

1. All power blower, cut off all the fuel supply。
2. The gas pressure is lower than the specified value, cut off the gas supply。

• The performance characteristics of

1. This series of boiler has the following characteristics: the boiler adopts double drum "D" type is decorated, convection bank expanding in water drum。
2. Boiler using the bearing way, can free up inflation。
3. Furnace wall and convective flue are all made of the diaphragm wall structure, good sealing and effectively reduce the use of refractory brick and maintenance workload, order to ensure the stability of coal bed methane combustion。
4. This boiler outer packing USES suppress sheeting, good appearance, beautiful。
5. The boiler furnace is equipped with inspection hole, provides great convenience for use and maintenance. The roof has two explosion door。
6. With high heat resistance materials as insulation blanket, heat preservation performance is good。
7. Tail arrangement has the economizer, can effectively reduce the exhaust temperature, boiler thermal efficiency is high。
8. Boiler heating surface has a surplus, and big enough space for soda, guarantee the stability of the boiler parameters。
9. With continuous electric adjustment, water supply and has high and low water level alarm, interlock protection function。
10. Use water spray attemperator, adjust the temperature sensitive, thermal control。

（11）* * stable operation range of the boiler：

Gas pressure: 2800 pa,


Heat load: 70% 100%.


In addition, the front panel to install the burner mounting plate and the self-closed mouth shape selection of burner is designed according to the original design, if choose other burner, it can be installed by the department at the scene of the user to change according to the installation of the burner specifications.
