Condensing steam marto pj boilers evaporators and condensers john wiley sons new york 1991 worth the user to select three reasons advanced heat transfer technology, fuel combustion, low emissions of nitrogen oxides ...... condensing steam boiler with its obvious technical advantages in many hearts and minds of business users. Condensing steam boiler thermal wear because of the major characteristics of the boiler itself and products stand out, it is becoming a public company recognized and selected mainstream boiler. Here follow the fast boiler together, to understand why users choose to use the steam condensing boilers better. 1, easy maintenance overhaul internal boiler set up more than 10 monitoring probes, water pressure, water temperature, power supply and other parts have made a key protection, and intelligent control room connected to the probe, once the site of abnormal or failure to monitor the problem, immediately activation of the alarm, timely remind the operator to check the status of the boiler. For joints and other mechanisms to protect the relatively weak position, also set up manholes and hand holes for easy inspection and maintenance technicians later. 2, intelligent user interface condensing steam boiler start-up and adjustment is through the intelligent touch-screen direct operation, clear user interface resolution, Chinese characters makes clear, the entire boiler operating status are clearly show, including flame boiler temperature changes and changes in the state level and the like. 3, rational design SCIENCES condensed steam boiler is able to have good thermal efficiency, high-temperature steam can be permanently output, mainly due to the structure of a scientific and rational design. For example, a tail is provided in the flue economizer and a condenser, not only can improve the thermal efficiency of the boiler (more than 105%); also reduces exhaust gas temperature (220 deg.] C or less reduced from 100 ℃). Excellent quality considerable thickness (28mm) of the panel ND steel material, filling the gap between the centrifugal glass wool, have a good seal to protect the boiler and the insulation properties during use in a great extent. The reason why users are keen to be seen using a condensing steam boilers, mainly due to the obvious edge, not only because of the full range of condensing steam boiler technology to improve the performance of outstanding features, energy saving and pollution-free and does occur in the use and supply sufficient heat, and in the whole repair and maintenance of equipment is very convenient, the fast will be able to deal with the problem by past record.
First, the implementation of the total coal consumption control
Accelerate coal mergers and acquisitions, consolidation pace of technological transformation, and resolutely eliminate excess capacity to resolve the coal. Before the end of 2018 to complete the county level and above cities restrict coal-burning zone and the coal area delineation work to strengthen the loose coal burning and fireworks control, prohibit the sale, banned the use of coal, petroleum coke, high-polluting fuels. Vigorously implement the "coal to gas," "coal to electricity" project, increase the proportion of electricity, natural gas in energy consumption. By 2020, the city's coal accounts for the proportion of energy consumption is reduced to 70% or less.
Second, to carry out comprehensive improvement of coal-fired boilers
Before the end of 2018, the central city out of 20 tons of steam per hour of coal-fired boilers, 35 tons of steam per hour to start the following phase-out of coal-fired boilers. Atlantic Town Center City led Xixiu on the wind direction, seven Town, Cai town official reference implementation of February 15, 2015 promulgated the "Anshun City People's Government on delineation of high-pollution fuel combustion zone ban of" 3.5 Kunming Shanghai high speed range on both sides of one thousand meters anshun prohibit new paragraph 35 tons of steam coal-fired boilers. By 2020, the county (district) total phase-out urban area and 10 tons of steam coal-fired boilers, basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment. Center City ban on new built-up area per hour and 75 tons of steam coal-fired boilers, county (district) urban area 35 tons of steam per hour ban on new coal-fired boilers and other regions 10 tons of steam per hour ban on new coal-fired boilers . Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage.
Third, improve energy efficiency
Continue to implement the action of the total energy consumption dual control and strength. By 2020, the city's yuan GDP energy consumption fell 14% in the region, the total energy consumption control in less than 28.55 million tons of standard coal, new energy consumption control in less than 100 million tons of coal. Strengthen the implementation of energy efficiency standards to promote, develop, promote energy-saving technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.
Fourth, accelerate the development of clean energy and new energy
As of 2020, the installed capacity of wind power reached 200,000 kilowatts; actively seek Zhenning County, Guanling County, Ziyun County PV poverty alleviation projects Indicators Program, to encourage qualified enterprises to implement photovoltaic bidding, led a group of farmers light, light forest project floor building.
Boiler surface quality of the weld quality of the weld surface of the marto pj boilers evaporators and condensers john wiley sons new york 1991 requires requirements: (1) should meet the dimensions of weld design requirements and technical standards, weld and base metal should be a smooth transition, is not less than the height of the weld surface of the base material . (2) the weld heat affected zone and the surface does not allow cracks, pores, craters, and macroscopic defects such as slag. Vertical (3) of the pressure element, and the circumferential weld seam stitching head no undercut, partially undercut the remaining weld depth of not more than 0.5 mm. Sides undercut weld pipe total length of not more than 20% of the circumference of the tube. (4) grinding the weld surface after the elimination of defects or mechanical damage thickness not less than the thickness of the base material. (5) on both sides of the slag and weld spatter must be removed.
Essential fuel combustion will produce a large number of CO2, NOX and SO2 and other substances, these substances emitted into the atmosphere, cause the greenhouse effect and acid rain, have serious damaging effects on the environment. Condensation marto pj boilers evaporators and condensers john wiley sons new york 1991 flue gas while condensing water vapor, the flue gas can be removed in these harmful substances. Therefore, the use of condensing boilers is also important to protect the environment.
