Industrial boilers are a type of special equipment. If you want to operate safely, you need assistance in many aspects, such as ensuring excellent quality when manufacturing boilers; paying attention to the installation of auxiliary equipment when transporting and installing boilers; and when using boilers. Pay attention to strictly follow the operating specifications, and so on. Here, Zhengzhou Fangkuai Boiler Factory would like to remind you that the "five major chain protection" of boilers cannot be ignored.
The "five major chain protections" of industrial boilers mainly refer to: high and low water level alarm devices, low water level interlock protection devices, overpressure alarm interlock protection devices, over temperature alarm interlock protection devices, etc.
For pulverized coal, oil and gas boilers, there are interlock protection devices that can automatically cut off the fuel supply when the induced draft fan is powered off, and the interlock protection devices that can automatically cut off the fuel or gas supply when the fuel and gas pressures are below the specified value. Ignition program control and flameout protection device, etc.
For hot water boilers, there are interlock protection devices that automatically cut off fuel supply and interlock protection devices that automatically cut off the supply and induced draft fans when the pressure drops to the vaporization pressure or the water temperature exceeds the specified value, or the circulating water pump suddenly stops running.
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).
