"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small boilers county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.
In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.
Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.
After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "
This year the city built-up area of the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.
City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
Natural gas boiler risers arranged in the corner of the room as much as possible the natural gas boiler standpipe arranged in the corner of the room, especially at the junction of two exterior walls. On each riser pipe, the lower end of the valve should be installed, turn on the water for inspection. For small riser systems can also be supplied only in the partial rings, valves coat return water pipe. Double-pipe water supply system is typically placed on the right side facing the riser when the riser and manifold intersects competent should bypass manifold. In addition to the stairwell and the auxiliary room (e.g., toilet, kitchen, etc.) can be combined with a standpipe, the standpipe is generally advised separately provided, so as not to affect the heating space at the time of inspection. Return water pipe can be laid on the ground, does not allow the laying of time (e.g., when married), or not enough headroom, return water pipe passage disposed in a semi-trench or trench on the floor to pass. There are two approaches, should be located at a distance from movable cover, married trench should be provided movable cover, in order to repair the pipe trench every backwater interlude. Return water pipes should also be noted that there is a certain slope to facilitate draining. In order to exclude the air in the system, gas-fired, current tank should be provided at the end of the water mains, and the tank should be set in a room or place provided with a drainage facility. If you can not meet this requirement, it should be put to a place near the trachea drainage facilities in order to exhaust. In order to effectively exclude air from the system, all levels of water in the pipe should have a slope of not less than 0.002, usually 0.003 (mechanical or gravity circulation aspect according to the given cycle, as described above). As a result of conditions, mechanical circulatory system of hot water pipes can be laid without slope, but the tube is not less than 0.25m per second water flow.
Fuel gas steam boiler ldr3-0 4r leak repair How? Valves leaking packing should be added to or replacement of the valve. If gas is leaking fuel steam boiler body to identify the reasons - if the leaking furnace boiler installation must have a professional team to go through the local repair of pot seized by the acceptance --- put to use in order to continue to be that, if a serious leak consider replacing the boiler.
Gas-fired steam boiler ldr3-0 4r and condenser boot speed is an important role: the specific types of boilers, the following will be involved in the learning process, which is a gas steam boiler, and its Web site is still in the boiler products, so, it is very necessary to be familiar with and understand, so, in order to become more familiar with the site and the manufacturer, and at the same time, to increase their professional knowledge, that is, so that they can benefit from learning, rather than nothing. 1. gas steam boiler start-up speed, and whether important? Gas boiler steam boiler this kind, which is on the boot speed, from a professional point of view, is very important because, if the boiler starts too slow, then the result will be a waste of fuel, but also waste time, affecting the efficiency of the boiler, it will say that this is a very important, but on this issue, that the answer is yes. 2. Gas-fired steam boiler blowdown, if there is demand for boiler water level? Sewage work gas steam boiler, which during the course of this particular aspect of the water level, there is a requirement, the main, for the water level should be maintained at around 60%, in order to carry out sewage work, otherwise, can not be of. And when its emissions, there must be someone responsible, and closely observe the water level changes, to prevent water shortages.
