DZL series chain grate coal fired steam boiler, is a kind of horizontal three-pass water tube and fire tube shell boiler, the left and right side water cooling wall of furnace is radiation heating area, both side of flue and thread fire tube of inner boiler drum is convection heating area. Front and back furnace wall and both side of water cooling wall made up of refractory bricks. Use light chain grate add fuels mechanically, and equip with blower, draft fan for mechanical ventilation, also equip with scraper slag extractor for discharging the ash automatically.
This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate, has the advantages of feed mechanically and strong adaptability of different fuels.
1)This coal steam boiler works with biologic gas making method. And there is a water logging dust cleaner on the boiler, it can decrease the output waste gas and dust.
2)The boiler can work automatically according to the users setting program.
3)Our protected device is safe and reliable. Selecting superior pressure controller, safety valve, low water alarm,
4)Stable operation,high quality steam and high thermal efficiency.
5)Boiler itself has dedusting effect, which makes the boiler soot discharge reaches the national environmental regulations indicators.
6)It is simple to clean slag only after burning completing.

Features of automatic control and fault protection
Boiler steam pressure automatic regulation system
When the control system of the boiler steam pressure automatic regulation system enters the working state, when the necessary conditions for combustion are satisfied:
When the steam pressure in the pot is higher than or equal to the set upper limit of pressure, the control system outputs the stop signal.Until it stops burning.
2 Feed water control:
When the system is working and normal, start the feed pump, the water pump is working, and the water level differential pressure transmitter detects the water level signal to keep the water level of the pot stable.Ensure the quality of steam.
The water level regulating instrument shows the boiler water level.
3. Manual control: The water pump can also be manually controlled by touching the key on the control panel.
Fault alarm and protection
The control system can monitor the current working condition of the gas-steam boiler in real time and carry out real-time and comprehensive intelligent fault identification and treatment.The control system can diagnose and deal with the following faults in real time:
1. Protection of extremely high steam pressure: When the steam in the pot is overpressured, the control system will immediately enter the chain, and sound and light alarm will be given, and the screen will display "extremely high steam pressure".After the fault is eliminated, press the reset button to break the chain.
2. Water shortage protection in the boiler: in case of extremely low water level failure due to pump failure or other reasons, the control system will immediately shut down the burner's power supply, enter the chain, and alarm with sound and light, and the screen will display extremely low water level.After the fault is eliminated, press the reset button to break the chain.
Ultra high boiler water level: when the water level in the pot is higher than the upper warning level, sound and light alarm will be given.Prompt "ultra high limit of water level in the pot", the display screen prompt drainage.Automatic recovery after the fault is eliminated, stop the pump without stopping the furnace.
4. Overload of water pump motor: heat relay action when the water pump motor is over current, cut off the power supply of the water pump motor, and stop the water pump, which is realized by hardware.
Power failure: In case of power failure, the control system will immediately shut down the power supply of all equipment in the cabinet where power failure occurs.When the power is restored, the cabinet will be in the off-duty state automatically. It is necessary to restart the machine and start the equipment to ensure the safety of the equipment.
1.What is the size of furnace door and blower hopper?
Size of furnace door:
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500
2.What is the combustion mode of coal/biomass fired boiler?
The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
3.Material of boiler drum / steel plate / tube.
Boiler drum material: Q245R,carbon steel, executive standard: GB713-2008
Tube material: 20# seamless steel pipe, carbon steel, executive standard: GB3087-2008
Still kettle material: Q345R, alloy steel, executive standard: GB713-2008
4.What is the height of chimney?
The chimney is usually 30m, irrespective of the special circumstances.
5.What are the heat-resistance temperature of grate and furnace?
The heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1100℃, and the lower temperature could be 700℃.
6.What is the temperature of smoke gas?
The highest temperature of smoke gas is 165℃.
7.How long can the coal/biomass fired boiler works?
Coal/biomass boilers could work for 10~15 years, under correct operation, high water and coal quality, etc.
8.How to avoid collapse of bricks, and what should be done if it happened?
When boiler installation finished, drying the boiler according to the manual, it’s very important to avoid collapse of bricks.
9.How many stokers do I need for one boiler?
Usually 3 person, every 8 hours a shift.
