electrical steam boiler 300 kg consumption
Pharmaceutical Purchasing steam boiler needs to pay attention to what pharmaceutical procurement steam boiler boiler needs to pay attention to what is currently used in the pharmaceutical market is quite extensive, so the choice of making more use of pharmaceutical boiler steam boiler, then the following small as we share it is recommended to buy pharmaceutical boiler. Most generally used to disinfect pharmaceutical use in a boiler, dryer, decoction of Chinese medicine, etc., when making the selection, are generally considered to purchase the boiler, operating costs; run hot boiler efficiency; auxiliary boilers configuration; Boiler air consumption and so on. Generally, the purchase price and operating costs of the boiler, mostly inversely proportional. If the quality of the boiler, thermal efficiency, the use of technology, process and so more good then its pre-acquisition costs will naturally be relatively higher, but on the long-term operating costs, these excellent boiler once put into use within two to basically we can achieve this effect within three years back; on the contrary, if the cost of the lowest view of the boiler, there was no short-term run accident went to the choice, once the future problems, the consequences are relatively large. For pharmaceutical factory, its products are closely related with the human body, so when selecting a greater need to consider long-term, comprehensive consideration and analyzed. In addition, it is necessary to emphasize that the current technology is the use of boilers, emission standards. Different boiler manufacturers, the use of technology are not the same, good boiler manufacturers use the technology, the standard is often considered relatively high, basically covering various aspects boiler thermal efficiency and emissions and gas consumption and other considerations. For pharmaceutical these institutions is concerned, the cost of boiler operation, efficiency will directly affect the cost of production in factories and production efficiency, etc., it is to say the two are closely related. In short, for the pharmaceutical steam boilers to buy this one, small series that removing price than the purchaser's standing position that we should consider, as well as the overall efficiency of this piece, the perfect combination of the two, might choose to really fit our application easy and quick steam boiler.
Group R & D Center came to the exhibition hall, Mr. Liu Wei, president listened carefully throughout the various sectors, gathered to watch the exhibition hall to show a number of unique patented quick way of sound and light equipment, and careful inquiry of the current business development and marketing state. Also president of the company's current situation, the future direction of development, all kinds of high-end manufacturing equipment and remote monitoring system with unique features made a quick side centralized reporting.
Reason for the early start to strictly control the boiler speed boost: The boiler starts, steam after the ignition is due to the water wall tube absorbs heat generated. Vapor pressure is due to the increasing amount of steam production is increased, the saturation temperature of the steam drum water with elevated pressure is increased. Since the saturation temperature of steam at a lower pressure to pressure change rate is high, the initial boost pressure rise value is very small, the saturation temperature of the steam will increase a lot. Boiler start early, natural water circulation is not normal, low flow rate of water or a lower drum local stagnation, heat water in contact with the drum wall is exothermic, the heat transfer coefficient thereof is small, so the lower metal drum wall temperature rise small; upper drum due to condensation heat of the steam drum metal wall, so the higher the temperature of the upper metal drum, thereby causing the lower drum wall temperature compete phenomenon. Since the drum greater wall thickness, and is formed in an outer drum wall temperature high-low phenomenon. Thus, excessive steam temperature will increase due to uneven heating drum and a greater temperature difference between the thermal stress, seriously affect the life of the drum. It must be strictly controlled speed boost at the beginning of the boiler starts to control the excessive temperature.
Gas hot water boiler 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.
