Boiler flue gas at a dew point of about 55 ℃ (excess air coefficient 1.15), only the medium is heated to a temperature below 55 ℃ recovering heat of condensation in the flue gas heat recovery in order to achieve better results at 30 deg.] C or even less . In the field of the central heating, hot net return water temperature above 50 ℃, flue gas can not sufficiently recover the heat of condensation. This method of addition of the condensing heat exchanger directly in the tail gas boiler is often only partially recovering the latent heat of the flue gas, the heat of condensation can not be achieved depth recovery.
Traditional centralized heat cogeneration district heating transmission pipeline has been lengthened increasingly unable to fully meet the needs of urbanization in the heating market, while large areas of fog and haze has promoted the huge demand for clean heating. At present, the main methods of cleaning heat pump technology, solar energy technology, electrical technology and the Valley of the gas heating technology, and as more and more abundant supply of natural gas, heating comfort has been formed in the northern heating area, as well as the South demand areas of the city and not have central heating, the use of natural gas distributed energy heating has a wider range of adaptability. However, the traditional large energy gas boiler, in the era of high gas prices, high operating costs hampered the large-scale application of gas heating.
ZG Boiler is the market leaders manufacturer in CFBB coal fired boiler technology, supplying boilers with capacities of up to 600+ MW for independent power production, combined heat and power production, and industrial applications,such as coal fired CFB in India textile plant.
For the 2018-2019 autumn-winter air pollution prevention and control work, Jinhua City, Zhejiang Province issued a public draft, mainly in the autumn and winter to reduce heavy pollution weather Development frequency.
Take measures to reduce coal comprehensive, non-electric focused on reducing the total coal consumption, in 2018 the city's total coal consumption reduction of 1% compared with 2015. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption of the same amount of capacity reduction or substitution, elimination of energy consumption, water consumption, environmental protection and safety is not up to 300,000 kilowatts coal-fired units. Development of industrial parks "One District One heat source" action plan, and more than 300,000 kilowatts coal-fired units were heating transformation, promote backward and shutting down small coal-fired thermoelectric integration of coal-fired boilers in the range of 15 km radius of the heat. Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, to the new "coal to gas" projects, should adhere to increase coal gas reduction synchronized to gas will change, the premise of the gas supply contract signed and orderly implementation.
Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation to ensure that no dead ends, no blind spot. Investigation and the coal-fired boilers to register one by one.
According to the law to increase the city's efforts to phase out coal-fired boilers in accordance with regulations. Before the end of December 2018, the city basically out of 10 tons of steam per hour of coal-fired boiler, built-up areas out of 35 tons of steam per hour coal-fired boilers. Complete 1 set (Yiwu) per hour, 40 tons of steam coal-fired boilers transformation of ultra-low emissions, coal-fired plants to achieve ultra-low emission levels.
In principle, the boiler NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. New installation and reconstruction of gas-fired simultaneously supporting the low NOx combustion device.
Biomass boilers to carry out a comprehensive investigation, complete control of boiler scale, distribution, fuel, furnace, pollution control facilities and pollutant emissions, and establish a list of management accounting. Yan Gesheng biomass boiler registration, strictly control the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of biomass boilers ultra-low emissions transformation. For existing biomass boilers, environmental inspection carried out one by one, there are multiple distributed biomass boilers, the implementation of the demolition of small and large industrial agglomeration area.
Clean Steam has been used throughout this course, and is used in the ISPE Baseline Guide, it is not used universally, and can have different meaning to different people. Terms such as Pure Steam, Pyrogen-free Steam and Low Endotoxin Steam are encountered in the pharmaceutical industry, andLearn More
Aug 22, 2018 · Super heater is another important part of Feed Water and Steam Circuit of Boiler. Super-Heater is an important element of the feed water-steam circuit. It is basically a heat exchanger in which heat is transferred to the aturated steam to increase its temperature.Learn More

directly back to the Cornish boilers of the early nineteenth century, invented by the British inventor and mining engineer Richard Trevithick (17711833). Early steam boilers such as the wagon, the haystack and the egg-ended boiler worked at low pressures (less than 0.7 barg) and were used to drive pumps at mines,Learn More
Objective: To describe and explain the boilers functions and the two main types of boilers. What is a boiler? A water containing vessel in which water is heated under pressure Transfer heat from a fuel source (oil, gas, coal) into steam The steam or hot fluid circulates out of the boiler for use in various process or heating appliances.Learn More
The steam generation rate in these boilers are low i.e. 9 tonnes per hour. For a given power the floor area required for steam generation is more and it is about 8 m 2 per tonne per hour.Learn More
The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure obtainable is limited by their large shells to about 300 psi. Fire-tube boilers are used for heating systems.Learn More
Steam boiler is nothing but a closed vessel combustion chamber which generates steam at a desired pressure by the combustion of fuel to water. Steam is supplied to the steam boiler in differen field like steam engine, steam turbine, thermal power plant,various heating installation process,different cotton mills,sugar factories etc.Learn More
Steam for Power Generation Superheated Steam . If saturated steam is further heated, its temperature goes on increasing beyond the boiling point. Such steam, with temperature higher than the boiling point at that pressure is called as superheated steam. It is always recommended to use saturated steam for process application and superheatedLearn More

Steam locomotive - Wikipedia. 2019-10-27 · A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine.These locomotives are fueled by burning combustible material usually coal, wood, or oil to produce steam in a boiler.The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers).Learn More
Jul 22, 2019 · A steam boiler is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed steam boiler and worked at low to medium pressure (1300 psi or 6.8952,068.427 kPa) but, at pressures above this, it is more usual to speak of a steam generator .Learn More
