Gas boiler shutdown normal shutdown process step is one step in the process of boiler operation is essential to understand the shutdown processing methods to ensure more long-term operating life of boiler. When the boiler the following faults can temporarily shutdown for maintenance. Expansion port, leakage rivet joints; tube, the waterwall tubes, damage to the heating surface tube leakage; drum in contact with the flue gas, set top box, a heat insulating material off the downcomer; water supply system, a combustion system, the occurrence of breakage safety accessories . Shutdown of the gas boiler normal (full shutdown, maintenance shutdown) Step 1, in order to stop the burner, for closing the valve. At the same time feed water to the boiler, 2cm above the normal water level reaches the stop water supply, reduce the pressure. 2, close the main steam valve, open the traps, steam boiler, water cut off. 3, the electric boiler feed water control valve closed and the manual valve, boiler feed water cut. 4, steam pressure may be lowered to the water supply and drainage operations alternately 0, the pot water temperature is gradually lowered. When the temperature dropped to 50 ℃ (not hot when hand potshell head with or touch), the entire pot of water may be drained. Should be preceded by opening the drain valve or air valve above the boiler, this time into the furnace maintenance, shutdown must be kept slow cooling, rapid cooling is prohibited. From the shutdown to be able to enter the furnace maintenance, cooling time is not less than 24 hours. 5, sales of more than 24 shutdown, to total gas supply valve is closed, opens the gas pipe to completely drain the subjective dispensing gas.

First, before regularly shutting down boilers and inspecting electric furnaces, the following three aspects of preparation should be done: The main contents are as follows: (1) consult the technical file of boiler retrofit electric furnace registration and understand the use of boiler retrofit electric furnace. In order to make the boiler reform electric furnace inside and outside inspection, the general need to know: boiler transformation electric furnace design, manufacturing, installation situation; boiler transformation electric furnace transformation situation; boiler transformation electric furnace operation history and use situation; Boiler retrofit electric furnace water treatment, boiler rules and regulations implementation, and so on.

2) the preparation for stopping the furnace before inspection. First, according to the maintenance schedule, the furnace shutdown date is arranged, and then the boiler revamping electric furnace is shut down according to the normal shut-down procedure, so that the furnace is slowly frustrated. The cooling method can be adopted by injecting gas to dissipate the sinking water, replacing the furnace water for cooling, and cooling by ventilation in the in-line furnace. When the temperature of the furnace water drops to 70 ℃ 80 ℃, the water can be discharged. Open all the doors. When opening the door hole, prevent warm water, steam suddenly spurts out to burn people. The steam, feed water and sewage pipes in the furnace are separated from the corresponding pipes in the boiler revamping furnace in operation. The baffle used for partition should be strong enough to avoid being bulged out by high pressure media. Break position Clear instructions should be given. The flue which is connected with other boiler revamping electric furnaces should also be reliably separated. In addition, it is necessary to remove the soot and scale on the heating surface of the boiler retrofit electric furnace.

3) preparation of inspection tools and lighting. In order to ensure smooth inspection work, inspectors should prepare the necessary instruments, tools, gauges and safe and reliable lighting.

Fuel steam boiler outstanding advantages which fuel steam boiler itself also has a lot of performance characteristics, fuel steam boiler according to the purchaser at the time of manufacture were manipulated interested in a lot of optimization. It can provide a good and convenient for the buyers. What next for us to see the outstanding advantages of fuel steam boiler. A very high degree of intelligence intelligence high fuel steam boiler itself, can take the initiative to implement soot blowers and electric ignition and other operations according to the purchaser's command, particularly in the operation of credible smooth, also occupied off the fail-safe device to reduce security problems. Second, less occupied with gas flame spoiler, can enhance heat transfer, greatly reducing heat loss, as many buyers who use less gas, and buyers are also particularly easy to manipulate when using the process does not require It guarded, save more time and effort. More fuel steam boiler section featured strongly recommended, after the above said, it is not there with this device we have a lot of understanding. When the next election thermal effect device, it is also going to be many.

Inside the Fangkuai boiler plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.
