How To Restart A Boiler Safely After Summer
Many boilers may be stopped during summer and start operating from autumn to winter, especially some hot water heating boilers. No matter how the boiler perform before, it should be checked thoroughly to ensure normal operation of it from then on. Many problem may occur during its in-operation time, such as electrical faults, water leakage, tube corrosion or others we can not imagine.At that time, the entire system must be carefully checked before the boiler is placed in operation. Boiler operators and other responsible personnel, such as supervisors, must be up to date on current codes and procedures.
Check the safety device
The safety devices on a boiler is the most important parts that ensure the normal and safe operation of boiler, such as the temperature meter and the pressure meter on a steam boiler and the water level indicator and temperature meter on a hot water boiler. With these devices, we can know the operation condition of boiler clearly and so we can guarantee the safety and efficiency of boiler. Many accidents are owing to the neglect of inspecting.
Check the water tube of boilers
The water tubes may corrode during the in-operation time of boiler because of water inside and outer factors. During the daily operation, we should also inspect them and change the tubes that leak water. For steam boiler, for example circulating fluidized bed boiler for central heating in winter, the corrosive tube may lead to failure of boiler, even explosion, which cost a lot to maintain. Besides, change the damaged tubes guarantees the high efficiency of boiler and save cost for industries.
Check the combustion system
The direct factor that affect the efficiency of boiler is combustion system, it will affect the combustion condition of full. Fully combustion of full is help to energy saving, environmental protection. For large scale boiler, such as circulating fluidized bed boiler, the high efficient whirlwind separator should be paid more attention.
Besides these main parts, every operator should review the Manufacturer's Operation, Maintenance, and Instruction Manual for operation instructions and familiar with the timing sequence of the automatic controls. Then do a thoroughly start-up check or ask an expert or engineer in boiler making for help if necessary.
