As far as we understand fast what is the heating surface of the fire tube boiler, Qinhuangdao City, Hebei Province to respond positively to tackling air pollution control actions, and intensive phase-out of coal-fired boilers. May 22, Qinhuangdao City Funing District launched the first action, a paper mill for a six tons of coal-fired steam boiler on-site demolition work. By Comrade Sun Guosheng, deputy director attended the action, and announced that coal-fired boiler central demolitions began.
Party Secretary Sun Zhichuan, Wang Hua district leaders to direct the demolition work, the Municipal Bureau of ecological environment, the ecological environment Branch area, technology and industrial Information Bureau, staying Town, elm Town, the next village management area, Funing town and other relevant units attended centralized demolition action.
The demolition operation was eliminated Qinhuangdao unified action to ban coal-fired boilers, Funing District is the city's main venue for the implementation of this action. 2019 coal-fired boilers area demolished 33 sets of objectives and tasks is that this concentrated action demolish 14 units, 12 sets of new coal-fired boiler investigation, a total of 26 sets of 248 tons of steam coal use is expected to reduce the amount of 149,444 tons, 145.73 tons of sulfur dioxide reduction , 439.37 tons of nitrogen oxides, soot 37.36 tons.
The third reason: the reason why the structure design is scientific and reasonable condensing steam what is the heating surface of the fire tube boiler can have the good heat effect to carry on the long-term heat energy supply, also mainly because the boiler is scientific and reasonable in the structure design can make it use well. For example, the installation of economizers and condensers at the rear end of the factory can not only help improve the efficiency of condensing steam boilers, And the well-selected panel material greatly ensures the sealing and thermal insulation performance of the whole condensing steam boiler.
What is a gas what is the heating surface of the fire tube boiler? It refers to a gas-fired boiler fuel gas boiler, comprising a gas water boiler, gas hot water boiler, gas and steam boiler. Gas boiler furnace tube inspection before use, furnace, pipe tobacco, and other head and bracing member whether the normal pressure, presence or absence of left severe corrosion or deformation, cracks, presence or absence of scale in the furnace, impurities, and other objects or absence of tools including, at the same time, confirmed that no one in the boiler, before closing all manholes, hand holes, into the hole, hand hole, the lid, the lid being put should, be asbestos mat with a rubber ring or between the manhole cover asbestos rope asbestos rope prepared pad.
Boiler expansion tank disposed what is the heating surface of the fire tube boiler expansion tank is provided on the boiler pressure almost essential, they can absorb thermal expansion of the boiler water and can increase the heat generated by the volume of the boiler water to prevent the pump is evacuated, upon receiving further occurs when the pump stops, the valve opening and closing or closing cycle hysteresis hot water flowing back and closed tightly. Expansion tank arranged to be noted that the following questions: 1, the expansion tank space shall amount is greater than the net water-swellable systems; 2, tank expansion space must have a vent to the atmosphere, the vent diameter not less than 100mm, in order to ensure that the boiler operating at atmospheric pressure; 3, the tank can not exceed the elevation of the top of the boiler 3 m diameter pipe connected to the boiler is not less than 50mm; 4, in order to prevent the hot water boiler is filled with water spills, the expansion space in the tank at an overflow that allows for high level pipe, overflow pipe should be connected to a safe place. Also, to facilitate monitoring the liquid level, water table should be provided; 5, add water throughout the hot water circulation system can complement the expansion tank from the boiler, the boiler can share a few boiler expansion tank. These are the boiler expansion tank setup,
Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.Get A Quote

Fire-tube boiler A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.Get A Quote
