1. Control system

Equipped with a microcomputer controller dedicated to hot water boilers, a large-screen full Chinese LCD screen with super-bright backlight and the boiler operation status is clearly visible no matter day or night. Complete display: working conditions of the circulating pump, working conditions of the burner, temperature of the boiler water, water level, current time, alarm records, etc., boiler operation status is all available; easy to set up: after the boiler is turned on, the operator can enter at will through 6 keys Standby state (setting), entering the running state (starting up), exiting the running state (stopping), and freely set the operating parameters while in the standby state; full-featured: can set the current time, alarm temperature, water temperature upper limit temperature, Water temperature lower limit temperature, circulating pump on temperature, circulating pump off temperature, boiler on / off time (can be divided into 4 time periods) and other operating parameters. Usually, the operator only needs to press the “Start” key to start the machine, and press the “Stop” key to stop, which is very simple.

2. Combustion system

Imported burner, fully automatic programmed control, automatic fan blow, electronic automatic ignition, automatic combustion of oil and gas, automatic ratio adjustment of wind oil (gas), good atomization effect, full combustion, energy saving and environmental protection, and having flameout protection device to ensure Burning safety. Under normal circumstances, the output of the burner automatically adjusts the length of the flame with the boiler temperature. When the boiler outlet temperature reaches the set value, the burner automatically stops burning. When the temperature is lower than the set value, the burner automatically starts to work. When the fuel, air intake is abnormal, the fault light is on, the program control device will immediately stop outputting fuel, and the burner will automatically stop.


3. Furnace design

The structure of the boiler is designed according to normal pressure, and the top is provided with a vent hole. The boiler works under normal pressure to avoid the danger of explosion. The boiler body adopts computer optimized simulation design to completely optimize the size of the boiler and make the shape coordinated and beautiful. The CLHS vertical boiler adopts a burner under-combustion method. The fuel is burned in the furnace tube at a slightly positive pressure. The high-temperature flue gas undergoes radiative heat exchange in the furnace tube, then enters the pyrotechnical tube convection heat exchange, and is discharged through the upper smoke box. The baffle is inserted in the flue pipe, which slows down the exhaust gas speed and strengthens the heat exchange to ensure that the heat generated by the fuel combustion heats the furnace water to the greatest extent, greatly improving the thermal efficiency of the boiler; the CWNS horizontal boiler uses a full wet back three-pass Structure, long flue gas flow, lower smoke exhaust temperature, full corrugated furnace tube setting, strong flame disturbance, strong increase of heat transfer coefficient, and effectively preventing the reduction of equipment life due to metal thermal expansion and contraction; large caliber smoke The gap between the tube and the large-hole bridge makes the boiler’s scale coating thin and easy to clean in equal time.

4. Multiple protections

The boiler has multiple safety protections: Leakage protection means that the power is automatically cut off when it leaks electricity; overheating protection means that when the boiler water temperature exceeds the alarm temperature, the burner is automatically stopped and an alarm is issued; secondary overheating protection means that when the boiler shell temperature exceeds 105 ° C, it is automatically cut off In the secondary circuit, the boiler stops working; the anti-dry burning protection means that the sophisticated water level electrodes monitor the water level in real time. For other reasons, when the boiler water level reaches or falls below the extremely low water level, the boiler stops working to prevent the danger of dry burning.

5. Thermal insulation performance

Glass wool is used for whole body insulation, light weight, good insulation effect, and low heat loss.

6. Overall appearance

White color plate packaging, beautiful and generous, good sealing, rust resistance, mechanical and electrical integration, small footprint, easy to use.
