threaded pipe hot water boiler
When such inspection revealed a large area of the furnace wall damage, and will hob and the furnace wall temperature, must be shutdown for maintenance, such as alternate furnace is not in operation, the furnace can continue to operate, but the load must be reduced, increasing the combustion the negative pressure chamber, and pay close attention to the furnace wall, where the hob, the hob as a negative pressure is increased after the temperature rises to shutdown immediately exceeds 200 ℃.
2, when the wind is insufficient furnace, boiler combustion chamber and the upper portion of the top frame and the high temperature furnace, boiler load at this time to reduce or enhance the wind, and maintaining appropriate negative pressure in the boiler combustion chamber.
3, with adequate ventilation, reduce the temperature of the combustion chamber refractory bricks, the bore may be increased excess air to reduce the temperature.
4, when the external walls of the furnace with protruding phenomenon, should pay attention to whether it is likely to continue to develop, as not only the development and the destruction of the wall when the furnace should be shutdown for repairs.
Industrial Steam boiler in Saudi Arabia
A wet-back Horizontal industrial steam boiler uses a water cooled turn around zone (end closure). A dry-back design relies on fire brick or refractory lining to prevent the end closure from overheating.
It is reported that the atmosphere and do in Hebei Province recently issued issued a "coal-fired boiler upgrade Hebei three-year battle plan" (hereinafter referred to as "Plan"). "Plan" put forward, will continue to increase efforts to eliminate 35 tons of steam / hour and coal-fired boilers, as of 2020, the province's 35 steam tons / hour and the boiler "No Coal", while steaming retains 35 t / h coal-fired boiler and above the implementation of energy efficiency retrofits to mention environmental protection.
2017, Hebei cities (including Dingzhou, Xinji) built-up area for 35 steam tons / hour and coal-fired boilers, the county seat 10 steam tons / hour and coal-fired boilers basically completed "clear" work. 2018, the province plans to phase out a total of 6764 units 13466 tons of steam coal-fired boiler, stove and stove operating a small coal stove, have been eliminated as of September 35 steam tons / hour and coal-fired boilers 6141 Taiwan 12485 tons of steam.
Next, Hebei will focus on the implementation of nine key tasks:
First, actively promote central heating facilities, industrial parks and accelerate the elimination of coal-fired heating boilers, the implementation of "the big-generation small" and "a garden a furnace" governance program, organized industrial wasteheat special action.
Second, increase clean energy alternatives, optimize energy structure boiler. As of 2020, municipalities and districts and counties built-up area of straight pipe central heating and clean energy heating rate of 100%.
Third, increase the coal-fired boiler energy conservation and environmental protection to enhance the transformation efforts.
Fourth, increased pollutant emissions and coal quality management and control efforts, deepening the boiler control. For reservations of 35 steam tons / hour or more coal-fired boiler to install air pollution automatic monitoring facilities and networking with the provincial and municipal environmental protection department.
Fifth, to accelerate the application of new energy technologies, promote demonstration projects mature. Require municipalities to develop clean energy development plan, and carry out the heating boiler can too + + PV, geothermal pilot, accelerating wind power demonstration heating Zhangjiakou region, to promote biomass energy, gas, alcohol-based fuel, industrial waste heat, light hydrocarbon fuel and other types of energy.
Sixth, give prominence to coal-fired boilers "Gas", "electricity" management. Municipalities To plan, implementation of the "gas will change," "power given to change." Heating boilers complete transformation of all time ahead of the end of August, without access to gas, clean energy power light before shifting coal-fired heating boilers can not be removed.
Seven, to carry out comprehensive environmental remediation coal-fired boilers, the implementation of grid management systems.
Eight new boiler strict access, strict implementation of pollutants and reduce the amount of times the coal alternative system. By the end of 2018, the province's coal-fired boiler control in less than 110,000 tons of steam.
Nine, strict boiler exclusion criteria, norms and acceptance transformation.
Notes before you start to run steam boiler must be a comprehensive inspection of the steam boiler Sheung Shui, are under no abnormality can be put into use. Today small briefly one of the few issues Notes ----- Steam Boiler Feed should be noted that, with the view of the following: 1, the required water quality steam boiler, boiler water hardness is too high if the site should be supporting water, complete treatment can reduce fouling of demineralized water hardness of boiler tubes, thereby increasing the life of the boiler to reduce operating costs. 2, Sheung Shui, when should slow to add water inside the steam boiler feed water temperature is not too high. 3, add water, not too much, as the temperature of the water will continue to increase expansion, resulting in waste. Generally, add water to the normal water level of the water line also is the middle line on it, now supporting the steam boiler above all intelligent devices in Sheung Shui, simply open the smart addition of water it can be had. 4, to put inside the boiler economizer and air inside the boiler duct excluded when water was added. 5, after the Sheung Shui to see whether the water level in the water level dropped, there may be drain valve not closed tightly reason, you should check the steam boiler population during the Sheung Shui, welding flanges, pipe is leaking phenomenon exists, if found leaking immediately stop adding water and appropriate treatment.
