bvfw domestic boiler

Configuring steam bvfw domestic boiler feedwater and steam boiler feed water equipment device points in claim 4 points: water supply system (1) of the steam boiler, should ensure safe and reliable water supply. (2) steam boiler should spare water supply equipment. Arrangement and number of units and capacity of backup water supply system of water supply equipment, should meet the following request: ① boiler steam boiler should be at most two vertical work to pump ** (one spare). ② Two capacity to pump, not less than 120% of the nominal overall operation of the boiler and the amounts of evaporation. ③ When the boiler room above three feed pump apparatus, which feed water total capacity should be: when the maximum capacity of a feed pump deactivation, the remaining capacity can always run parallel to the pump is not less than the rated boiler all running evaporated 120% of the sum of the amounts. (3) to the pump head (i.e., height of the water column required to overcome the static pressure of the respective dynamic pressure) should be greater than or equal to the algebraic sum of the following: ① water pressure drop difference water supply system (water column hydrostatic) and the water supply system. ② hot water boiler safety valve at the design pressure set pressure. ③ economizer system pressure drop drum. ④ The above three multiplied by the algebraic sum of the amount of 1.05-1.1 rich as appropriate.

Gas hot water bvfw domestic boiler maintenance needs to pay attention to what in the course of the gas condensing hot water boiler, ongoing maintenance is an important part, how to do maintenance work? The main contents are as follows: (1) prior to use, Boiler Tube respond to a simple check to see whether the blockage or corrosion leaks. (2) boiler during operation must be standardized, rigorous operation, while prohibiting non-professionals abnormal operation of the boiler. (3) the gas in the course of hot water boiler, auxiliary boiler and, in particular, safety, efficiency and thermal energy associated condensing device key components and boilers, maintenance should be performed regularly. (4) In addition, according to the seasonal variations, different maintenance measures to be taken, for example, when taking into account the winter frost questions to explosion-proof tubes and other phenomena occur, resulting in unnecessary boiler accident. Above, Zhengzhou fast editing as you do a simple share, hoping to help you.

Vertical steam bvfw domestic boiler fouling does not clean up what impact will produce? Vertical steam boiler in use, water use has not been softened, so prone to fouling, the need for timely clean up, otherwise the long-term accumulation continues, the rough surface layer structure, it is easy to adhere to the slag particles and Vertical steam boiler buried security risk. Here's a look not cleared up scaling will have less adverse effects. 1, reduce boiler thermal efficiency of high-quality and reliable vertical steam boiler, though they have good thermal efficiency, but if the boiler scale long-term clean-up, which can lead to fouling of boiler thermal conductivity drop, heat transfer performance of the boiler heating surface also will be reduced accordingly, it is released during fuel combustion heat can not pass all the water into the furnace, so will not only increase fuel consumption also reduces the thermal efficiency of filtration, leading companies use the boiler cost increase. 2, the boiler will be affected due to the security vertical steam boiler thermal conductivity is reduced after fouling, scaling at the local temperature of the metal tube wall will rise sharply, if the temperature rises beyond the tolerance range of the metal, occurs creep, so that the strength of the metal shell boiler is reduced, then at the operating pressure of the boiler, where the metal will drum kits perforation and rupture phenomena, affecting the safe operation of the vertical steam boiler. 3, reducing the volume of each boiler steam output of the boiler furnace are fixed, when the vertical steam boiler furnace fouling will occupy a certain space, so that the fuel consumption of the boiler will be limited, the generation the amount of heat and steam will be reduced, so the vertical steam boiler output is reduced. Thus, if the fouling produced in the vertical steam boiler is not timely clean-up will have a lot of adverse effects, therefore, the need for all businesses to use the boiler, not only want to buy well-known to use vertical steam boiler, also to develop cleaning cleaning cycle, prevent the pot to increase the amount of scale to produce a variety of adverse effects based on usage and water quality conditions of the boiler.

We learned from Anshan City Bureau of the ecological environment: to improve air quality living environment for urban residents, according to government requirements, Anshan external publicity of the built-up areas and industrial parks and a list of more than 10 tons of coal-fired bvfw domestic boilers, municipal environmental protection department also welcome all citizens supervision, to provide the city's built-up areas and 10 tons and above boiler clues industrial park outside the list.

Battle to lay the blue sky, the city has in recent years embarked on a built-up area and the city's industrial park and 10 tons of coal-fired boilers out of work, the city built-up areas and industrial parks and 10 tons of coal-fired boilers demolition of all the reservation coal-fired boilers to achieve discharge standards. As requested, before the end of 2020 in the city of Anshan City will be built-up areas and industrial parks all phase-out over 10-20 tons coal-fired boilers, coal-fired boiler units involved should be prepared in advance.

To further enhance the quality of atmospheric environment, promote environmental management to raise the overall level, in accordance with the requirements of the provincial government, the city of the city within built-up areas and industrial parks and more than 10 tons of coal-fired boilers information for publicity. These publicity boiler will be included in the list of key sewage units, strict supervision, to ensure the discharge standards.
