After purchasing a steam boiler, many users do not allow the boiler to run continuously throughout the year. They will decide whether they need to shut down or restart the boiler according to their company's demand for steam. So, what preparations need to be done before restarting the steam boiler? Zhengzhou Fangkuai boiler manufacturer reminds everyone that ventilation and purging must be carried out. As for the reason, let's look down.
Ventilation and purging before the start of the steam boiler is to avoid the remaining combustible gas or pulverized coal in the furnace after the previous shutdown. It may also be because the fuel system is not tight during the shutdown that the combustible gas or pulverized coal leaks into the furnace. When burning, once the torch is inserted into the furnace, if the concentration of combustible gas or coal powder is within the blasting limit, it will cause the furnace to blast, damage the furnace wall, and even cause personal injury. Before burning, start the induced and blower fans, insist on 10%-25% of the rated air volume, and control the ventilation time at about 5 minutes.
Although ventilation with large air volume cannot completely remove the combustible gas or coal remaining or leaking into the furnace, it can dilute the concentration of combustible gas or coal in the furnace to a lower limit far less than the blasting limit, and then ensure the boiler combustion Time equipment and personal safety. After the ventilation is over, the combustion should be carried out as soon as possible to avoid leakage of the fuel system, and the concentration of combustible gas or coal powder in the furnace will rise again to the blasting scale.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
