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.

Recently, Shaoxing, Zhejiang Province, the municipal government issued "on the issuance of Shaoxing new coastal air quality standards carry special action program" (the "Notice"). "Notification" is mentioned: a ban on new biomass boilers, nine companies continued to promote the transformation of low-nitrogen gas boiler.

4. The built-up area to carry out bulk coal campaigns to strengthen the use of bulk coal production and life behavior of businesses and residents a comprehensive investigation and persuasion, to ban briquette production and sales, and increase legal coal quality supervision, strict penalties for substandard coal burning behavior.

2. carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management, development of industrial furnaces depth remediation, complete elimination of the task assigned by the city. Strictly implement the relevant emissions regulations, can not reach the relevant requirements, the implementation of cut-off regulation.

3. Conduct brick kiln depth remediation, strict implementation of emission standards, enhance on-site inspection of law enforcement, monitoring, focus on examination of the "three simultaneous" implementation and pollutant emissions, on-site monitoring of the discharge port sulfur dioxide, nitrogen oxides, particulate matter and other pollutants .

About six tons of steam boilers have to say things the state, more than 6 tons and 6 tons of steam boilers must be used continuously Sheung Shui, is to use the pay frequency, which is something that many customers do not know, not many manufacturers configuration, so there will be a lot of trouble in the future use. 6 tons of steam boiler is actually one hour 6 tons of water can become steam boilers 6 t 6 tons of steam boiler is also divided into several categories. Mainly based on six tons electric steam boiler fuel or category 6 tons of gas steam boilers 6 t gas steam boilers 6 tons of fuel steam boiler 6 tons of biomass steam boiler in 2012, gas steam boiler is a market leading product, because of his operating costs the lowest point for businesses and institutions, it is very good. But since 2012, worsening haze situation, the state began to ban gas boiler, just before the start of the implementation of the first-line second-tier cities, has now spread to all parts of the country, do not let all the gas boiler use, do not gas-fired boilers , and can only choose several other fuels, which will promote the development of gas-fired boiler, gas boiler gas boiler is the best alternative, whether it is from the running costs of environmental protection or from above, are the national key advocate of. So for now, the use of gas-fired boiler is the best way. However, there are many places they can not use gas-fired boilers, because they have no gas supply, how to do, so that both the development of the oil-fired boiler, oil-fired boiler due to make his run Chen this high, very few selected customers, but in the absence of gas supply where they had to use, so there is no way. Biomass Steam Boiler In fact, he is a walking a fine line, biomass boilers due to his fuel does not contain S, P these magazines, so relative to the gas he is more environmentally friendly, but his smoke is very large, and gas-fired boilers as also the need for a good filter to filter his smoke, and biomass boilers not all places are so used, so the choice of the boiler when it is best to consult your local government and ask whether the use of the environmental Protection Agency, or else is not into the approval procedures of the program. Come to talk about electric boiler, he is the highest operating costs, but also the most environmentally friendly boiler, no chimney, a 6-ton electric boilers hour the 4300 degrees, most people can not afford to burn, he rarely do 6 ton, are generally used occasionally in the following two tons.

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.

Electricity Generation using Steam Turbines

2018-11-21 · Conventional Energy Generation. The first practical electricity generating system using a steam turbine was designed and made by Charles Parsons in 1884 and used for lighting an exhibition in Newcastle. Since then, apart from getting bigger, turbine design has hardly changed and Parson's original design would not look out of place today.
