hot water heater boiler

Steam hot water heater boiler appeared to bring great help we all know, the steam boiler is to provide people with high-quality steam main machine. In the past, steam appeared to mankind has brought great changes. Emergence of the age of steam introduced the era of modern human civilization. Now there steam boiler once again that human potential is unlimited, it appears to be very helpful people. Steam boilers plays an important role in people's lives. It's like bathing, eating, and other industries. It is said that need steam boiler where it is needed steam. Steam boiler to provide steam main tools. Industrial steam boilers provide steam for the production people at the same time providing power for human production, making it easier to produce in production. Steam boiler to provide steam in life can help people make food, and why we can take a bath with a steam boiler in the cold winter. These are provided to help steam boiler. Steam boiler can easily provide a better steam for us to make our lives more convenient and faster. For steam boiler, we note that maintenance work should be used so that it can help us longer. Industrial production is the main driving force of world development, is very important for the development of the world. Therefore, we need to use steam boilers provide steam better for us, because our human development needs to help these advanced machines. The machine age is not a primitive society. When humans learn to use tools, it has begun to have marked the beginning of civilization. Steam boiler is a tool that can help us human development.

Yesterday we learned that the Guangdong Province to increase pollution control efforts by the provincial people's government approval, Guangdong Province Market Supervisory Authority, the ecological environment of Guangdong Province, Guangdong Province, recently issued jointly approved by local standards "hot water heater boiler air pollutant emission standards." Compared to the original standard, including contaminant particulate matter, sulfur dioxide, nitrogen oxides, etc. received strict emission limits help to further reduce the total emissions of air pollutants.

Provincial Department of environment-related offices responsible person, the current Guangdong Province "Boiler Air Pollutants Emission Standards" promulgated and implemented more than eight years, with advances in pollution control technology, emission control requirements of its apparent leniency. Meanwhile, Guangdong air pollution control task is arduous, urgent need to close strict standards, further reducing the total emissions of air pollutants.

Guangdong "boiler air emission standards" in the context of the implementation province domain for coal, the material forming the fuel oil, gas and raw fuel 65 tons of steam per hour and less steam boilers, hot water boilers of various capacities and Heat Transfer Material Heater; stoker various capacities, stoker furnace.

The new "boiler air pollutant emission standards" (DB44 / 765-2019) to adjust six major areas.

A clear the raw fuel material forming air pollutants emission limits fuel boiler;

Second, the received strict emission limits boiler air pollutants, increasing the emission limits coal boiler mercury and its compounds;

Third, the abolition of provisions different emission limits by functional area and boiler capacity;

Fourth, in particular an increase of atmospheric pollutant emission limit requirements;

Fifth, increase the fugitive emission control requirements;

Sixth, the excess air ratio conversion flue gas pollutants to the atmosphere of pollutants emission concentration of the reference oxygen content conversion, the oxygen content of the clear reference atmospheric pollutants fired boiler burning biomass.

The new standard in the province gamut execution, the execution time of the specific step-wise: new boiler effect since April 1 this year; the transformation of boilers give some time, depending on which region, from 1 July 2019 2020 or the date of July 1 implementation of the new standards.

What is the condensate recovery? Why steam condensate recovery steam system is an important measure energy? In industrial production, steam as an extremely versatile energy and almost all businesses are inextricably linked. A large number of industrial water and coal-based energy is used to generate steam, and steam is used to heat industrial production process, the steam generated in the heat releasing section condensed water is often thrown away. Condensate has a large amount of heat, usually accounts for about 20 to 30% of total calories steam, some devices may be up to 40%. Thus if the temperature condensate as hot water heater boiler feed water recycling or secondary flash steam utilization, not only to save the water for industrial use, but will save a lot of fuel. Thus, in the production of the same multi-boiler steam, it can save 30% to 40% of fuel, water and water treatment chemicals. At the same time reduce fuel economy of boiler flue gas emissions, protect the environment. Condensate Recovery Value Embodiment: A thermal energy recovered in condensate water, the secondary flash steam heated steam produced can be replaced with a new material; B water saving, cost saving water; C high temperature condensate as boiler feed water, the boiler heating saving makeup water consuming fuel; D vapor condensate as boiler feed water, a lower TDS content, reducing the number of boiler blowdown, heat loss is reduced sewage entrained; E reduces smoke emission and waste water contamination of soil and groundwater . However, industrial steam condensate recovered faces many technical challenges, such as the recovery pump cavitation at high temperature condensate; closed directly boiler feed water; recovering the vapor-liquid two phase flow; contaminated condensed water recovery; high-temperature condensate and boiler feed water at room temperature the temperature of the water supply caused / pressure and poor. HUAWIN (China News) company as the world's leading experts in the steam treatment, using its own patented technology, customers can not only provide complete condensate treatment programs and products, and provides turnkey services and EMC, as do their Chinese energy conservation contribution. Condensate Recovery mode 1. Open the recovery, recycling closed 2. Direct recycling, indirect recycling 3. Restore recovery, heat recovery, flash recovery 1, closed recycling unit: There really grasp the closed recycling technology manufacturers very little , a true closed-recovery units, should address the following questions: 1) to ensure no leakage at the same time, when the incident level is too high to solve the overflow drain problem, that is, when the drain, the same can not leak. 2) stop after an accident, pour water through the cooling tank, the tank may have a negative pressure when the device is restarted, it may cause the pump suction side pressure is too low, it is necessary to solve automatically eliminate the negative pressure in the tank The problem. 3) high-temperature condensate water pump cavitation may cause problems at runtime. 4) When the condensate pump is turned on, the vortex is easily formed, the flash vapor suction pump inlet. 5) the secondary flash steam condensation problems inside the water tank drawn out. Only real solution to the above problems, in order to be truly mastered the core technology of closed recovery. 2, steam-driven pump: HUAWIN (China News) Steam Pump Company truly master the core technology, in addition to the key components are imported, the parts using CNC machining centers precision machining, precision brand has more than similar imported products. And it has developed a large flow pump, a single pump can deliver water to reach 35t / h.

While its heating system can be used for long-distance transportation pump, heating large radius, however, the heat transfer coefficient and lower thermal efficiency. Low cost which adapt to a wide range of high temperature steam, heat transfer area of ​​the apparatus can be reduced, reducing the cost, but since the steam condensate recovery heat medium difficulty, can cause vaporization of some of the water avid waste. At the same time, even if there is condensate recovery, because the recycling process, and other magazines oxygen doping should the water, it will cause harm to the hot water heater boiler.
