Boilers play an important role in many production systems in factories. To achieve optimal efficiency, users must understand the rules of boiler operation correctly, safely and to protect the boiler for good operation. The following article will provide you with the basic knowledge you need to know when operating a boiler.
Check the boiler system
Before operating, you need to check that all valves, hand pump, intermediate water supply tank, water tank, piping system… all are installed correctly or not, ready to step in. active or not. It is necessary to consider whether all the parts involved in the process have any problems or not, to avoid being passive during the operation period.
Boiler drying and boiler alkaline
After installing the boiler, it should not be put into operation immediately, but should be dried and alkaline. This is a step to help clean grease, rust, dirt on the inner surface of the boiler, dry the brick, mortar, and insulation of the furnace.
Make a fire in boiler
Close the exhaust valve, steam valve, safety valve, water supply valve; open the air discharge water pump valve, boiler water supply valve, water pipe circulation valve, three-way valve of three manometers. Check the water level in the soft water tank, if the water is dry, the furnace will not start. Put fuel in the combustion chamber. Proceed to burn fuel. Making a fire is finished when the boiler pressure is reached to the limit pressure and the furnace operates smoothly and technically.
In the boiler operation technique, after a fire is completed, the operation of the boiler is very important. We need to regularly monitor the boiler’s combustion mode, to ensure that the fuel is completely burned, there should be no black smoke.
When the pressure in the furnace is close to the maximum working pressure, prepare to supply steam. Note that when supplying steam, the combustion mode must be stable.
During the operation of the furnace, we must keep the water level in the boiler stable, should not be operated for a long time at the lowest or highest limit. The boiler is periodically supplied with water through an intermediate water supply tank or a hand pump.
Stop the boiler
Stopping the boiler is done by closing the steam supply valve and the steam release valve to the atmosphere by channeling the safety valve, gradually releasing the pressure of the furnace, adding water to the furnace to raise the water level of the furnace to the highest level. water pipe. Stop providing heat to the oven. Let the oven cool slowly but keep constant supervision.
Above are the safe boiler operation skills you should know to ensure safety. Hope this article has brought you useful information.
