In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired mikael seifu boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
The main advantages of steam as a heat transfer medium is: 1, low cost, wide adaptability, can meet the different requirements of the various pressure and temperature of the heat requirements of the user simultaneously. 2, non-toxic, can be directly heated food, even if drip, nor harm on the environment. 3, a high steam temperature, a large latent heat of vaporization, the heat transfer area can be reduced relative to the hot water apparatus, and reduce costs. 4, small thermal inertia, heat faster when the steam supply, while the cold steam stop something else. Since the heating medium steam condensate recovery is difficult, resulting in waste and water latent heat. Even with condensate recovery, condensate recovery in the process, because water easily dissolved oxygen and other impurities, but also easy to cause harm to the mikael seifu boiler. Oxygen to the water, salt and other impurities cause boiler fouling, corrosion and other problems affecting the safety and energy efficiency of the boiler.
Condensing steam mikael seifu boiler used to warm the pipe does not cause local low pressure condensing steam boiler steam suddenly not send warm the pipe inner steam pipe freezes, forming a localized low pressure steam condensate entrained impact to a lower pressure, water hammer occurs waterhammer pipe can deform bad shock, damage to insulation, the pipe can be serious when shattered. Thus the steam must be sent before the heating pipes. Condensing steam boiler before the heating pipe, the first open all traps on main steam line discharging condensate accumulated in the steam pipe, and then slowly open valve main steam condensing steam boiler of about half a turn (or slowly opens the bypass valve), so that a small amount of steam into the pipe, so that the temperature gradually increased, until the pipeline is fully warmed up and then condensing the steam boiler main steam valve is fully open. Isolation valve between the conduit and the boiler when the boiler is running simultaneously several, when a new condensing steam boiler into operation if the main steam isolation valve is connected to the main steam pipe valve also require heating pipes. Warm-operation may be performed in the above stated method, it may be open all the trap before the main steam valve and the isolation valve in the condensed steam boiler Stokes, using steam generated in the boiler during the boost to slowly warm. With the boost heating boiler pipes and boost heating up, so not only eliminates the need for time to warm the pipe, but also safe and convenient. Single boiler operation. The steam pipe is not long, this method may also be employed for heating pipes. When heating pipe, such as pipe expansion and found to support and hanger has not normal, or large shock sound, indicates that the temperature rise is too fast heating pipe, the steam supply to be slow speed, i.e., slow down steam valve opening speed, to extend the warm-time. If the sound is too large earthquake, steam valve should be closed immediately stopped and opened the big trap to warm the pipe, to be carried out to identify the cause and then eliminate the fault. After heating pipe, closing the trap on the pipe. After preheating steam pipe, the steam supply can be carried out, and the furnace.
When selecting and purchasing mikael seifu boiler sensors, we should consider which types of boiler sensors should be determined according to the measuring object and the measuring environment. The principle of the sensor must be considered first, which requires an analysis of various factors before it can be determined. According to the characteristics of the sensor to be measured and the conditions of use of the sensor, consider the following specific issues, the size of the measuring range, the measured position of the sensor volume requirements, the measurement mode of contact or non-contact, the method of signal extraction, Wired or non-contact measurement, the source of the sensor is imported or home-made and many other factors. The second is the choice of the sensitivity of the boiler sensor, usually within the linear range of the sensor. The higher the sensitivity of the sensor, the better, when the sensitivity is high, the output signal corresponding to the measured change is larger, which is beneficial to signal processing. The sensitivity of the sensor is directional. The sensor with low sensitivity in other directions should be selected when it is a single vector and its directivity is high. If the sensor is measured as a multi-dimensional vector, the lower the cross-sensitivity of the sensor is, the better.
