Characteristics of gas heating boilers
Gas heating boilers are also called gas heating boilers and gas heating boilers. Gas heating boiler refers to a boiler that uses gas combustion to heat the boiler water to meet people's heating. The gas includes natural gas, city gas, liquefied gas and biogas.
Let's take a look at what are the characteristics of gas heating boilers:
1. The control system is equipped with a special computer controller for the gas heating boiler. The operating status of the boiler is clearly visible.
The controller screen display is complete: the working condition of the circulating pump, the working condition of the burner, the temperature of the boiler water, the level of the water level, the current time, the alarm record, etc., and the operating state of the boiler is readily available;
Convenient setting: After the boiler is turned on, the operator can enter the standby state (setting), enter the running state (starting), exit the running state (stop) through 6 buttons, and set the running parameters randomly while in the standby state;
Full-featured: It can set the current time, alarm temperature, water temperature upper limit temperature, water temperature lower limit temperature, circulating pump opening temperature, circulating pump closing temperature, boiler switching machine time (can be divided into 4 time periods) and other operating parameters. Usually, the operator only needs to press the button to start the machine, and press the Stop button to stop. It is very simple.
2, burner, automatic program control, automatic fan cleaning, electronic automatic ignition, automatic combustion of oil and gas, automatic proportional adjustment of wind oil (gas), good atomization effect, full combustion, energy saving and environmental protection, with flameout protection to ensure combustion Safety. Under normal conditions, the burner output automatically adjusts the length of the combustion flame according to 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, abnormal air inlet, etc. occur, the fault light is on, the program control device will immediately stop outputting the fuel, and the burner will automatically stop.
3. Furnace design The boiler structure is designed according to normal pressure. The top is provided with atmospheric holes. The boiler works under normal pressure and is away from the explosion hazard. The boiler furnace body is optimized by computer simulation, which fully optimizes the size of the boiler and makes the shape harmonious. . The CLHS vertical boiler adopts the burner under-burning mode. The fuel is burned under the micro-positive pressure in the furnace. The high-temperature flue gas is radiated and exchanged in the furnace, and then enters the convective heat exchange of the pyrotechnic tube, and finally discharged through the upper smoke box. The flue pipe is inserted with a baffle to slow down the flue gas discharge speed, strengthen the heat transfer, ensure the heat generated by the fuel combustion to maximize the heating of the boiler water, and greatly improve the thermal efficiency of the boiler; the CWNS horizontal boiler adopts a full wet back type three return process. Structure, long flue gas flow, lower exhaust gas temperature, full corrugated furnace setting, strong flame disturbance, strong heat transfer coefficient, and effectively prevent the life of equipment from decreasing due to thermal expansion and contraction of metal; large diameter smoke The gap between the tube and the large hole bridge makes the scale coating thin and easy to clean in an equal time.
