The basic configuration of the heat of the gas steam boiler steam boiler and service method is natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace released heated pot water, and allowed to vaporize into steam heat conversion equipment. Water in the pot is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the expansion of the water vapor inside limited dynamic pressure generated heat is formed as an energy source is widely used. Steam boiler fuel burn-up and to ensure that the flue gas outlet temperature was cooled to a safe value convection heating surface of the work; using the heat of the flue boiler feedwater heating, in order to reduce exhaust gas temperature, fuel economy and functions. Each fired industrial steam generator for sale heating surface and joined together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. Gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. Water temperature should be close to the furnace temperature. Must regularly inspect the low water cutoff maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. Require periodic sewage operation, at least once a day, after the sewage drain valve should be checked because of possible contamination and leaks; if it must be excluded. When shutdown is not maintained while the steam pressure, the steam space of the boiler will produce negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened.
Boiler Room universities loss to deal with the past most colleges and universities are using a large steam boiler to produce steam for the canteen, water, bathing and heating, where steam is needed where to send, it is a waste. Now with fine design: Principles Steam steam equipment, water equipment with water, with hot water apparatus, and use the nearest, so as to save energy, reduce the cost, the effect manageable. Many schools have been rebuilt by this idea, achieved very significant results, the general transformation of the cost can be recovered within a year. Steam canteen: finned pipe steam: steam plant to meet all requirements; water: gas water heaters + finned steam pipe; water: air source or a solar-based, auxiliary heating gas hot water unit. Partly because of the loss of boiler: 1. Low efficiency of the boiler itself, and after prolonged use efficiency decreases, because: furring furnace, burner efficiency drops, Slagging ashes. 2. duct body loss, loss of pipe insulation, pipe insulation damage after loss increased. 3 does not match the amount of steam, Mara car; a pressure in excess terminal mismatch loss. 4, water in large boilers, heat loss, downtime restarted great heat need; 5, bulky water tank, heat dissipation area, and the insulation layer and the insulation layer thick enough damage; new boiler efficiency up to 90% but after using the terminal, the effective utilization rate of less than 40% utilization rate is even lower for some time, as long as the use of large-tonnage steam boiler on the above factors can not be avoided. Hot water bath, hot water within 40-60 degrees, a low quality heat, is a high quality hot steam, heating with high-quality low quality heat, certainly uneconomical. Hot water bath solutions include: solar energy, heat pumps (air source, ground source), gas water heaters and the like. How specific choice, depending on use environment, temperature, sunlight time, gas prices, electricity prices and other factors, to analyze specific issues. Cafeteria steam boiler is the key to solve the problem of stopping, previous methods to solve: 1 steam boiler generally cost at least 300 yuan / ton, the school used for steam dealers by way of subsidies. 2. The direct-fired equipment is generally used, the thermal efficiency is generally not more than 40% .3 use in a boiler or regulatory edge pressureless fired industrial steam generator for sale, the same thermal efficiency only 40%, the cost is greatly improved canteen business operators, operating simultaneously also very troublesome. There are other issues: bulky, large footprint, small stand-alone power, need several more, no vapor pressure, high water content, water is not treated with the use of prolonged increasingly inefficient, short life. Now Resolution: With the LEADER gas steam and gas water heaters, boiler room can easily solve the problem of losses, so that the school canteen dealers can be satisfied. LEADER gas steam characteristics: 1, no boiler room, without the need to handle the boiler permits, without kotelshchik: This product volume of less than 16 l system, outside the scope of the Boiler and Pressure Vessel requirements. 2, the use of the nearest: loss of small pipe. 3, high efficiency: oxygen-free copper fin heat exchanger thermal efficiency of 93% .4, modular combination: according to different needs of users for the amount of evaporation, the amount of hot water, tailored. 5, steam pressure up to 1.4kg, fully meet all the requirements of steam college canteen equipment. 6, high-power, small size: the largest single power of 300KW, the volume is only (L * W * H) 1050 * 400 * 1200MM.7, safe: with multiple security protection. 8, the processor is configured softener: water softener use of efficient processor, effectively preventing thermal efficiency reduction unit and pipeline clogging. 9, transformation action, low cost: the use of this product were boiler, gas flow, gas pipeline generally without transformation, the use of other equipment and without transformation.
Boiler work principle in thermal power plant:Industrial boilers provide the steam needed during industrial production.Boiler generate high temperature and high pressure steam through the nozzle in turbine blades, the rotating blade and drive the generator rotor to rotate to generate electricity.
"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.
