1. During the start-up process of the burner, if the burner repeatedly alarms and locks, it should be found out the reason, find the fault and eliminate it, and then press the reset button to inherit the start. Note: The continuous press of the reset button should not exceed 10 seconds
2. If the burner is not successful in one combustion, the natural gas boiler induced draft fan should be restarted, and the second combustion can be started after 5 minutes of ventilation.
3. In the normal operation era, the burner close to the thermal equipment department (such as the connecting flange, etc.) will be very hot, to prevent the formation of burns. Do not place flammable materials in the vicinity to avoid causing fire.
4. During the operation of natural gas-fired boilers, it is necessary to closely supervise the working conditions of hot water circulation pumps and natural gas-fired boiler pressures, natural gas distribution bags, pipeline valves, pressure gauges, flow meters, and water
Industrial boilers will produce wastes that needs to be treated during the use process, which is what we mentioned of boiler blowdown. What are the methods for boiler blowdown?
1. Regular blowdown
1) The time interval and quantity of discharge depend on the test results of boiler water. It usually do not exceed 5% of the water supply.
2) When the regular blowdown is being made under high load of the boiler, the blowdown of the water-cooled wall header is generally not required to avoid affecting the normal water circulation of the water-cooled wall and forming a tube explosion incident.
2. Continuous blowdown
The amount of blowdown shall be determined according to the test results of the boiler water, and shall be completed by adjusting the needle-shaped angle of the blowdown tube.
The explosion-proof door of the gas-fired boiler is opened or broken when the combustible gas explosion suddenly increases the pressure, it then releases high-pressure gas to reduce the damage to the gas-fired boiler body and also ensure
The function of the gas-fired boiler explosion-proof door is usually reflected when the gas-fired boiler is ignited or running due to improper operation. For instance, the furnace is not purged before ignition, the furnace is still not purged even the ignition cannot successfully be lit, the nozzle is leaking, the fuel is not completely burned, and extinguished failure to cut off fuel quickly, etc. all of them may cause the furnace and tail flue to explode. Installing explosion-proof door for gas-fired boiler is to release the pressure to avoid the accident from expanding and also to ensure the safety of the industrial steam boiler when a slight explosion occurs in the furnace or flue.
If the boiler burner fails or is faulty, then your boiler is not going to be able to generate heat efficiently, or in the worst case not at all . As industrial boilers are in almost constant use they are built to be very robust and last for decades, nevertheless they can still have problems with broken burners from time to time. Burner pumps, heads and nozzles can all cause problems but a swift replacement should limit your down time.
There are many opinions on the best way to clean a steam boiler. One of the oldest ways is to dissolve a pound of tri-sodium phosphate (TSP) and a pound of caustic soda (lye) in water and pour it into the boiler. Let it cook for a few hours and then drain the boiler. If you can't buy TSP in your town, try a commercial soap called MEX. It works well and will not damage the rubber gaskets found in some boilers. However, before you clean any boiler, check the manufacturer's instructions for their recommendations.
First of all, we should consider the thermal insulation effect. The main function of a gas-fired boiler is to provide heat energy. Good surface packaging material can avoid heat loss and save the fuel. It is suggested to choose glass wool which has a good insulation effect.
Secondly, we should consider the boiler appearance. It is best to choose a white color plate package when buying a gas-fired boiler, which not only has a beautiful appearance but also has a good insulation effect.
Finally, we should consider the boiler size. Wrong boiler size will cause some unnecessary troubles.
