2 Ton 2000kg 150 Psi Waste Wood Fired Industrial Steam Boilers For MDF Production Plant
DZH type biomass pellet fired steam boiler is a horizontal three-return water-fire tube type boiler. A row of water-cooled wall tubes are arranged on the left and right sides of the furnace, and two sets of tube bundles are arranged in the drum to form two return paths. The boiler has sufficient heating surface and is equipped with a tail heating surface economizer. It is equipped with drums and induced draft fans for mechanical ventilation. Layered combustion.
This biomass steam boiler has high automation level, automatic adjustment of boiler feed water, high and low water level alarm, low water level interlock protection, and interlocking protection of lead and blower. Auxiliary auxiliary equipment is complete.
Structure
Technical features:
(1) The arch tube tube and the threaded tobacco tube are used to form the drum tube, so that the drum tube is changed from the quasi-steel body to the quasi-elastic body structure, the pulling members of the tube plate area are eliminated, and the stress is reduced. The pipe in the tube plate was changed from two return strokes to a single return stroke, which solved the problem of cracks in the tube sheet.
(2) The lower part of the drum is arranged with the rising pipe row, which eliminates the dead water area at the bottom of the drum, so that the sludge is not easy to deposit, and the high temperature zone of the drum can be well cooled, preventing the lower drum of the drum.
(3) The high-efficiency heat transfer thread pipe is used to obtain the effect of enhanced heat transfer, which achieves the characteristics of heating and boosting the boiler, and improves the thermal efficiency of the boiler.
(4), compact structure, compared with the same type of boiler, the external size is small, saving investment in the boiler house infrastructure.

Fault alarm and safety protection
The control system can monitor the current working condition of the steam boiler in real time, and carry out real time and comprehensive intelligent fault identification and processing.The control system can diagnose and deal with the following faults in real time:
High steam pressure protection: when the steam overpressure in the pot, the control system immediately enters the chain, and the sound and light alarm, the screen shows "high steam pressure".After the fault is eliminated, press the reset key to remove the chain.
Water shortage protection in the boiler: when the water level of the boiler is extremely low due to the pump failure or other reasons, the control system will immediately turn off the power supply of the induced draft fan and enter the chain, and the sound and light alarm will be given, and the screen will show the water level is extremely low.After the fault is eliminated, press the reset key to remove the chain.
Boiler water level is too high: when the water level in the boiler is higher than the upper warning level, the sound and light alarm will be given."Ultra-high water level in the pot" prompts, and the display prompts drainage.Automatic recovery after fault elimination, stop the pump and keep the furnace.
Pump motor overload: heat relay action when the pump motor overflows, cut off the power supply of the pump motor and stop the pump, which is realized by hardware.
Power failure: when power failure occurs, the control system will immediately turn off the power of all equipment in the cabinet where the power failure occurs.When the power is restored, the cabinet will automatically be off duty. It is necessary to restart the machine and start all the devices to ensure the safety of the equipment.
Application
Chemical industry, textile plant, rice mill, garment factory, livestock, farm, hotel, school, etc.
