Electricity and steam are almost required in every step of raw sugar process, especially in juice extraction, clarification, evaporation and sugar drying, good quality steam takes a crucial role. Thus selection of steam boilers and heaters paonta sahibs becomes very important for sugar plant.
Henan run Q & Gas Boilers (b) 1. Internal gas boilers and heaters paonta sahib drum Henan mainly those devices and how they effect the arrangement position A:?? Henan gas boilers with capacities of different parameters, it is not exactly the drum inside the device - like, now at high pressure and ultra-high pressure boilers drum example, describes internal devices, their arrangement and a major role. Along the length of the drum is mounted at both sides of a plurality of cyclones, each cyclone barrel top is arranged a louver (wave plate) separators, their primary role is to rise by the tube into a mixture of soda and water vapor will be the initial separation. In the upper steam drum, steam cleaning horizontal mounting plate, on which the cleaning water supply layer, when the steam passes through the water layer, put dissolved or carried vapor partial turn salt was dissolved in water, to reduce the steam salt. Near the top of the drum is provided with a perforated plate, a uniform flow in the ascending vapor drum, and the water vapor is further separated. About 150mm with the drum center line of the discharge pipe opening accident; continuous blowdown piping is provided at approximately 200mm port under normal water line, and then disposed below the dosing tube. Also installed at the entrance of the downcomer cross blade. To prevent a drop generating swirling nozzle causing drop tube bucket with steam. 2. Continuous outfall mouth Henan gas boilers are generally installed where? Why? How much sewage rate? A: Top nozzle Henan continuous gas boiler 200 is generally mounted on a drum at the lower 300mm normal water level (i.e., "0"). Since the pot of water evaporation continuously gradually concentrated in the vicinity of the surface of the water with the highest salt concentrations. Therefore, continuous blowdown piping port Henan gas boiler should be installed in the region of the maximum boiler water concentration to high concentration continuously withdrawing boiler water, supplemented with clean water supply, thereby improving the quality of boiler water. Henan gas boiler blowdown rate is generally about 1% of the amount of evaporation. 3. What pot of water treatment dosing in Henan gas boiler drum sense Answer: the pot to prevent the fouling, if simply to remove the water contained in the outer boiler feed water hardness, needed more equipment will greatly increase investment; and plus? cauldron blowdown, heat loss not only increase the working medium, can not be eliminated pot residue water hardness. Thus, in addition to using external boiler water treatment, but also on the water in the boiler pan dosing process, remove the pot residue water hardness, to prevent boiler scaling. The method of addition of phosphate which is in the pot of water, so that calcium and magnesium ions and phosphate ions bound water pot, Rong generating hard water precipitation sludge, sewage regularly excluded, so to maintain a certain boiler water phosphate, neither fouling and corrosion, but also to ensure the quality of steam. 4. What Henan gas boiler regularly sewage outfall aim is installed in the mouth where A:?? Because Henan pot of water gas boilers containing rust and dosing process water precipitated the formation of slag and other impurities deposited on the bottom of the water circuit, regular sewage the purpose of the water is periodically discharging slag and other impurities precipitate, increasing the pan of water quality. Periodically outfall generally located in the lower header, or concentrated water wall lower portion of the downcomer.
February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.
First, strictly control the total coal consumption
The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.
Second, to strengthen control bulk coal
Full implementation of the "Harbin coal pollution prevention and control regulations" to strengthen quality inspection of coal, coal quality testing organizations standardized sampling, testing system, improve the sampling frequency. Promote clean and efficient coal-fired boiler, wherein an alternative embodiment the biomass must be dedicated biomass boiler, burning raw material briquettes, installation efficient dust removal equipment.
Third, steadily promote clean heating
To promote priority to the development of clean coal utilization and clean energy use, urban urban central heating. Being difficult to cover central heating, gas heating and accelerate the implementation of electrical heating and other heating decentralized cleaning implement "coal to clean energy" units should be synchronized removal of coal-fired boiler, gas boiler for an alternative to the use of low NOx combustion technologies , gas boiler efficiency can not be less than two levels. 2019, clean heating rate of more than 60%; in 2020, clean heating rate should reach 70%.
Fourth, to carry out comprehensive improvement of coal-fired boilers
To develop a comprehensive remediation plan coal-fired boilers, the implementation of cleaner alternative to coal-fired heating boilers. 2019, the urban built-up area, county (city) county towns built-up areas out of 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal fired facilities; basic urban built-up area out of 35 tons of steam per hour coal-fired boilers; basically eliminated the urban fringe per hour 10 tons of steam coal-fired boilers; county (city) basically out of the city and county (city) financial support units (including township, village ) per hour, 10 tons of steam coal-fired boilers. By 2020, basically out of 10 tons of steam per hour urban coal-fired boilers; out of the urban built-up area per hour can not discharge standards of 35 tons of steam (or 29MW) coal-fired heating boilers. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired boilers.
Fifth, accelerate clean energy development
Orderly development of wind power, wind power construction layout optimization, to carry out decentralized wind power development and construction in the area have developed criteria. Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.
Henan using a gas boilers and heaters paonta sahib which benefits, Henan condensing gas boiler heat transfer technology, more durable life Henan gas boiler heat exchanger made of stainless steel, and reverse flow of the flue gas sufficiently radiation heat exchange. Normal boiler to heat the same, Henan gas boiler or in a reverse vertical heat exchanger, the heat exchanger comprising mileage relatively long-time heat including latent heat of vaporization swap out the primary heat exchanger is a finned tube forming a special stainless steel, without any welding, in a corrosive acid condensed water, the life of up to 30 years, up to 50 years of theory. Second, Henan gas boiler stepless adjustment of Henan premix combustion gas boiler technology, power of 13% to 100%, i.e. when lowering the external demand, so that the output of the boiler and can adjust itself to match the needs of the time, maintaining low load low heat demand, to achieve maximum energy savings. Ordinary staged combustion boiler, in order to meet the high output low demand, most of the time is a typical "big horse car" mode. Thermo-regulation by start and stop frequently, heat a big impact, affecting the efficiency and lifetime. Third, Henan gas boiler low pressure gas, save gas regulator station in Henan initial investment low pressure gas boiler can be used to reduce the gas infrastructure investments, ordinary boiler to a medium pressure gas, regulator stations must be located, high cost, but also has security implications.
