boiler fill valves

(10) is the boiler fill valves thermal efficiency related to the boiler load?

Full familiarity and understanding of the boiler is an important task and necessary, because it is an important and major product in the website, but also includes a variety of products, so there will be such a specific requirement. "-. So below, will proceed with this work immediately, to improve everybody's study efficiency.

Gas hot water boiler fill valves which has energy-saving measures in the heating hot water boiler heating boiler is the main force for how gas hot water boiler energy problem, we summarize some of the energy-saving measures, there is a need for a reference for a boiler unit. First, both the steam pipe insulation pipe, hot water pipe or a variety of devices with a number of heat pipes are more or less heat loss in the heat transfer process, therefore, it is necessary to transfer thermal insulation pipes; addition to the insulate the pipe to a certain extent also played a role in the protection pipe. In the choice of heat insulation material, to the following requirements. 1, to select a high thermal conductivity and good heat insulating properties of the material. 2, when the heat medium temperature greater than 120 deg.] C, and the insulation material should not contain organic combustibles; only when the medium temperature is below 80 ℃, before selection of insulation material containing organic matter. 3, less hygroscopic insulation materials, does not cause corrosion of the wall, easy to manufacture and have a shape, easy to install performance advantage. The thickness of the insulation layer is determined according to the following general principles. 1, to ensure that heat losses in the pipe a predetermined value or less, not exceed a predetermined value range. 2, the surface temperature of the insulation should not exceed 55 ~ 60 ℃. 3, insulation capital investment should be controlled at the cost of insulation and heat loss equivalent to the cost of fuel and less. It is noted that to minimize the heat loss of the heat transfer conduit, the pipe diameter should be as small as possible, and shorten the transportation distance, while it should be relatively small pressure drop. Of heating equipment and pipelines good insulation is an important energy-saving measures. Second, hot water heating effect is relatively better in comparison with other media, the use of hot water heating can save 20-40% of the fuel, since the hot water heating and does not produce secondary condensed water evaporation losses. Secondly, both steam and hot water heating pipes compared to heating pipes, heat loss caused by the former will be smaller because of the need for continuous blowdown steam boilers and regular sewage, while the hot water boiler requires only a small amount of sewage on a regular basis. Then, according to the change Boilers indoor and outdoor ambient temperature flexibly adjust the hot water temperature is provided, on the premise of ensure the quality of the heating, the purpose of saving fuel. Third, the full absorption of flue gas waste heat boiler flue will continue to exclude a large number of high-temperature flue gas, which will be part of the flue gas heat away into the atmosphere, causing heat loss. Therefore, the high temperature flue gas heat recovery, is an effective energy-saving measures at boiler heating. Fast boiler gas hot water boiler of painstaking research, launched condensing gas hot water boiler thermal efficiency of up to 108%. By adding recovery near the boiler flue condensation, latent heat of the high temperature portion of the heat collected flue gas, into the boiler for reuse, higher thermal efficiency, fuel will be reduced relative to the investment cost.

Shanxi Province to continue to improve and protect the environment, prevention of air pollution, with "Environmental Protection Law of People's Republic of China", "People's Republic of China Air Pollution Prevention Law" and other relevant laws, introduced the "Shanxi Atmospheric Pollution Prevention Act" ((hereinafter referred to as " regulations ").

"Regulation" is mentioned, Shanxi coal consumption will implement the total control system, and gradually adjust the energy structure, reduce the proportion of coal in primary energy consumption. Provincial People's Government will work with the energy department in charge of relevant departments, according to the needs of economic development, social and environmental carrying capacity of resources, the development of the region's total coal consumption control target.

First, governments at all levels to limit sulfur points, high ash coal mining. New coal mines should simultaneously supporting the construction of coal washing facilities, so that the coal sulfur content, ash content meet the required standards. Have been built in addition to the mining of coal mine belonging to low-sulfur, low-ash or coal-fired power plants have been in accordance with the requirements of discharge standards do not need washing outside, it should be a deadline for the completion of supporting coal washing facilities. When coal, gangue, coal cinder, coal ash and other materials, should take fire and dust prevention measures to prevent air pollution.

Second, the coal-fired power companies, coking, and other steel companies use coal shall clean production processes, supporting construction dust removal, desulfurization, denitrification device to reduce the generation and emission of atmospheric pollutants.

Third, the city government should promote cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion scattered coal-fired heating boilers, central heating pipe network coverage prior to the completion of use of scattered coal-fired and coal-fired heating boilers have been built can not discharge standards heating boilers, should be demolished within the prescribed period the city government.

Fourth, the Municipal People's Government shall be divided into districts to improve the quality of atmospheric environment in accordance with requirements, it will be designated urban area to ban coal region, and gradually expand. County (city, district) people's government can scoping ban on coal zone in accordance with the actual situation. Delineation ban on coal zone should consider the needs of life of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.

Fifth, governments at all levels should strengthen the management of civil bulk coal. Prohibit the sale, does not meet the civil standard of quality coal for coal, lignite ban, coal washing, slime and other low-quality coal use low-quality coal as a civilian.

Boiler maintenance electrical precautions electric boiler fill valves in addition to strictly purchase, use also requires practices, so as to avoid danger to the person. So how does it perform maintenance? Here to tell you about it a few precautions when maintenance: 1, electric boiler maintenance, must cut off the power, pressure relief. 2, the burner every two months to be removed from the electric boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. These are electric boilers attention when maintenance issues related to the introduction, in addition, we want to mention is that after the work is completed, to check whether the tools, materials, complete accessories, such as to prevent left in the furnace space inside. Someone delisted before leaving the job site after acceptance, and then do the maintenance records, to prepare for subsequent queries. Hope that the text content can be helpful to you, regular maintenance can extend the life of electric boiler.
