Chain Grate Coal Fired Hot Water Furnace Water Supply Automatic Control System

Large Heating Surface and Fuel Saving Industrial SZL Coal Boiler for Garment Manufacturing

Product Features

1. The boiler is divided into two parts, one part includes the boiler body and the steel frame upper furnace wall, and the other part includes coal hopper, chain grate, base steel frame and lower furnace wall. Except for the middle partition wall construction, the other components are assembled and shipped. The tail cast iron economizer and the air duct of the boiler are shipped with the furnace.

2. The burning part adopts light chain grate, and the two sides enter the air. There are six independent air chambers under the grate, and there are air conditioning mechanisms on both sides of the air chamber. The air is blown into the lower part of the base by the blower, and the mouth is adjusted by the wind. The machine enters the independent wind room.

3. The upper furnace wall is assembled and factoryized by the factory. The lower furnace wall is composed of refractory brick, silicate fiber and thermal insulation material. The fuel enters the furnace through the gate, and the coal slag falls into the slag hopper during the operation of the grate. Finally discharged by the spiral slag machine.

Features of product automatic control and fault protection
1. Boiler steam pressure automatic adjustment system
The boiler steam pressure automatic regulation system control system enters the working state, and the system works normally when the combustion conditions are met. Once the steam pressure in the boiler is above the set upper pressure limit, the control system outputs a stop signal until the steam pressure returns to normal.

2. Water supply automatic control system
The water pump is started and the water supply system works normally. The water level difference sensor detects the water level signal and keeps the water level of the drum stable, thus maintaining normal steam generation. At the same time, the water level adjustment meter can clearly display the boiler water level.

3. Manual control system

The pump can be manually controlled by the manual touch button on the control panel.

Fault diagnosis and processing system features

The system can monitor the current working conditions of the gas steam boiler in real time, and carry out real-time and comprehensive intelligent fault identification and processing. The control system is capable of diagnosing and processing the following faults in real time.
1. Steam pressure over-limit protection: When the steam in the pot is over-pressure, the control system immediately enters the equipment to stop working, and the sound and light alarm is given. The screen displays “Vapor pressure is extremely high”. Until the fault is eliminated, press the reset button to cancel the alarm state.

2. Water shortage protection: When the boiler has a low water level failure due to pump failure or other reasons, the control system immediately turns off the burner power supply, enters the interlocking state, sound and light alarm until the fault is eliminated, and then press the reset button to cancel the alarm state.

3. Boiler water level over-limit protection: When the water level is higher than the upper limit warning water level, the sound and light alarm. Prompt "the water level in the pot is too high", the display prompts drainage, and the pump starts to drain. The fault is automatically restored after the fault is eliminated, and the pump stops working.

4. Pump motor overload: When the pump motor over-current, the heat will continue to operate, and the pump motor power will be cut off.
2.5 Control cabinet power failure: When the power supply fails, the control system immediately shuts down all equipment in the failed cabinet. After the power is restored, the control cabinet needs to be manually started after it is determined to be normal to ensure the safety of the equipment.
