industrial steam boiler for hospital
Water tube boiler structure and characteristics (the horizontal double boiler drum water): double horizontal tube boiler drum mainly by the horizontal drum, convection bank, the waterwall tubes, and headers and other downcomer pressure components. A front portion of the boiler furnace, the furnace water wall are arranged four weeks; on the drum located at the rear lower horizontal furnace, connected by a bend between the two drum pipes. Chain grate combustion equipment to use, some of Pulverized or roaster, with superheater, economizer and air preheater. After entering the furnace by the high temperature flue gas flowing through the superheater convection pass over, and then down to an upwardly rising S-shaped transverse convection bank erosion, and then down to the upper folding back pass, the economizer, the pre-air heat, by the induced draft fan, chimney discharged into the atmosphere. Evaporation boilers generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 megapascals (MPa).
Since 2017, Yongji County, Jilin Province to respond positively to the State Council issued the "Air Pollution Prevention Action Plan" to carry out corresponding work strictly in accordance with national, provincial and municipal environmental requirements.
It is reported that out of Yongji County vigorously promote the renovation work of small coal-fired boilers, promulgated and implemented the "little out of Yongji County boiler work program" to develop "a furnace policy" policy, no longer approve new steam 10 t / h coal-fired boiler , while promoting the phase-out of small coal-fired boilers.
For small coal-fired boiler phase-out program has been effectively implemented, Yongji County Government has formulated "Yongji County eliminate small coal-fired boiler renovation award up approach", the county built area of active users to carry out remediation work out of coal-fired boilers by small standard for financial awards complement, after the introduction of premium policy, and in the mouth before the town government to convene Yongji economic Development Zone, the area held a small coal-fired boilers user related meetings, arrangements for specific phase-out management work, and to a great extent to promote the progress of small coal-fired boilers eliminated.
Since the initial carry out small coal-fired boiler renovation work in 2017 to the present day, Yongji county built-up areas out of a total of 59 small coal-fired boiler units, a total of 16 sets of 20 tons of steam / hour non-electric and coal-fired boilers intention has been completed to upgrade pollution control facilities renovation work.
General Electric boiler according to the size decontamination decontamination apparatus has the following two ways: 1, in the station equipment. Decontamination station generally higher, before the device is a heater or a return pipe, in order to avoid debris flowing into the heater; 2, device in the water supply pipe outside the station. Decontamination station at the well outside the home are generally small, typically in water supply equipment, equipment and some system, some system is not the device, it is to avoid the effect of debris into the user's radiator.
Modern development of intelligent eliminated a lot of backward production capacity, also introduced a more more advanced production equipment, gas-fired boiler is one of them.
