Similarities and differences vacuum hot water boiler and hot water boiler pressure hot water boiler in this analysis of the current one, the use of a vacuum hot water boiler and pressure hot water boiler are many, then vacuum hot water boiler and pressure hot water boiler What are the similarities and differences between it? Now, Xiao Bian take you a simple analysis. (1) Selection of the auxiliary pressure hot water boiler configuration are relatively stringent, the preferred option, and therefore the probability of failure will be relatively small, and need not maintain a vacuum, simply run under normal atmospheric pressure to , the operation is relatively simple, but relative to its vacuum boiler in terms of some of the more troublesome, but, with the continuous improvement of technology boiler, vacuum boilers now have a breakthrough progress on its drawbacks, at present, two each there are various advantages, specifically how to choose, you need to examine the actual situation. (2) during operation of the vacuum boiler to take into account the degree of vacuum kept, the linkage may be necessary correlation means, the degree of vacuum once damaged, there may occur an accident boiler; and pressure hot water boiler does not have this condition, however, If individual users according to the actual situation, without permission will be under pressure to use pressure hot water boiler, and that their safety is another matter. (3) Origin pressure hot water boiler will be more, and vacuum hot water boiler due to technical applications is relatively new, and therefore, can produce and produce operating thermal efficiency, higher operating level, which is part of the good reputation boiler manufacturers. In short, the process of vacuum hot water boilers and pressure hot water boiler in the running there will be many figured the place, we will naturally have many differences, during boiler selection, take me to their strengths, based on the actual situation, The merit-based election

PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of ​​coal to gas projects in recent years, the country's use of gas-fired boiler more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.

2. boiler technology energy-saving measures (1) strengthen the technological transformation of inefficient boilers. Due to our limited economic base, not all older boilers have been updated. For updates not included in the scope, efficiency is not high but there are more defective boiler should strengthen technological innovation. Technological transformation of industrial boilers, should try to achieve a multi-effect of the change is necessary to improve the thermal efficiency to save fuel, but also to increase output, reduce pollution and achieve civilized production, but also to adapt to burning low quality coal. (2) boiler should make full use of frequency control technology. When selecting the boiler pump and fans, are considered certain margin in the rated load, so that in fact the boiler operation, the fan and the pump flow is less than the rated flow equipment, are required to be adjusted. Is adjusted by adjusting the throttle in the past, i.e., OFF or the throttle opening degree smaller Importers baffles, the flow rate is reduced, but not significantly reduced motor power. Frequency is reduced by the drive motor speed, the motor output power decreases. Frequency control for pumps and fans, general can save 30% to 40%, the investment can be recovered through two heating season, at the same time, due to the deceleration operation, reducing mechanical wear and extend bearing life, improved mechanical reliability sex. (3) the rational use of automatic control technology boiler. Boiler operation, automatic control can improve boiler efficiency, energy conservation. In recent years, automatic control technology and the rapid development of computer control, and more Sheung drum water level automatic control device, automatic control and computer control the combustion process in the oil and gas boilers more general application, for Stoker, some boiler monitoring the use of computer rooms, manual adjustment is also received good results. Boiler automatic control and computer monitoring instruments should be simple, practical principle. (4) promote the use of heat pipe heat exchanger. At present, the domestic part of the boiler flue gas temperature is too high, a large heat losses, reduces the thermal efficiency of the boiler. Can effectively heat pipe heat exchanger flue gas heat recovery boiler, the gas - liquid heat pipe heat exchanger is mounted in the boiler feedwater heating flue, significant energy saving effect, only one heating season investment can be recovered for a heat exchanger. (5) using the condensing heat recovery boiler technology. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated, it does not consider heat loss in a high latent heat of vaporization of the fuel heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and water vapor to enhance the thermal efficiency, the condensed water can be recycled. (6) reasonable steam accumulator. The steam accumulator is an energy save type apparatus, steam accumulator principle is that when the boiler load is reduced, the excess steam is fed into the boiler the steam accumulator and the steam under a pressure becomes high pressure saturated water. When the heat load increases, the amount of evaporation in short supply when the boiler, reducing the pressure accumulator, i.e., the high-pressure saturated water is separated into a low pressure saturated steam and water vapor produced by the user for use. Steam accumulator fuel savings typically 5% to 15%. (7) The vacuum deaerator technology. Vacuum deaerator oxygen is an energy save type method. Currently, oxygen supply and drainage method use large industrial boiler thermal oxygen atmosphere. This method of heating water to boiling temperature should at atmospheric pressure, oxygen in the water to drain away. Thermal oxygen atmosphere has two shortcomings. First, the atmospheric pressure boiling temperature, consumes a lot of steam, the boiler to reduce the effective use of heat. A 10t / h boiler feed water heated from 60 deg.] C to 105 ℃, steam consumption about 0.7t / h. Second, because the temperature of the boiler feed water economizer to improve the average water temperature increase, reduce heat economizer temperature, exhaust gas temperature increases, heat losses increase. These two points are the thermal efficiency decreases. And when the vacuum deaerator, the degree of vacuum is maintained at 7.999kPa (60mmHg), as long as the water temperature is heated to 60 deg.] C can achieve the purpose of oxygen. This not only saves steam and reduces exhaust losses, thereby improving the thermal efficiency of the boiler. (8) boiler water treatment technology to promote imports. It is estimated that imports of internal boiler every knot 1mm of scale, the overall thermal efficiency of a decline of 3%, and imports affect the safe operation of the boiler, through effective water treatment technology and cleaning technology, imports of non-boiler scale operation.

Vacuum hot water boiler manufacturer tells you the trend of its development before the start of the first digression, say thirty blink of an eye we have to go to 80 after the thirties, we tend to consider the issues are becoming increasingly cost-effective, the same way use in a vacuum boiler body is the same, then our future vacuum hot water boiler should gradually toward which direction to meet the needs of consumers it? Xiao Bian gave you about the river south of the shares of fast production of vacuum boilers cost-effective reasons: 1, vacuum hot water boiler there is no swelling, explosion, risk of rupture, safe and reliable 2, a multi-purpose machine, can provide a boiler for heating water, domestic hot water, pool heating at the same time. 3, the design life of more than 20 years, can be placed in the basement and roof, the state authorities are not limiting. 4, efficient, low cost. 5, no scaling, corrosion and other phenomena. 6, than ordinary boiler small size. Modular and arranged in parallel, more efficient and reasonable operation of the boiler. You can only open when a willfully without having rated heat. 7, high degree of automation, building automation connection, unmanned management. Even if guarded, guards and without an operating license. Minimal training. 8, vacuum hot water boiler is slowly being accepted by all, mainly for civilian use, such as hotels, residential, office, bath centers, schools, shopping malls and other places. So the future of the vacuum boiler trend will gradually be applied to large and small areas, hotels, bathing, or a layer of building only need a small modular vacuum boiler can achieve the effect of four tons of coal-fired boilers, so What is still hesitant to inquire quickly it!
