In the design of vacuum hot water boiler, the problem should be noted that the heat medium water vacuum hot water boiler, the negative pressure conditions at the maximum temperature is about 93 deg.] C, the maximum temperature of the boiler water at about 80 ℃, the water temperature and therefore require more when high, the water temperature should be used in other types of high boiler; 2) vacuum hot water boiler heat exchanger tube diameter is small, generally about 10 ~, while not fouling the inner pipe, to prevent impurities clogging the tube system , other sources should be installed or filter before the boiler return pipe inlet; 3) vacuum hot water boiler design, according to the system pressure, the pressure parameter determining unit, to ensure that the working pressure of the pressure unit to meet the system requirements. Pressure relief valve is provided at the interface of the vacuum hot water boiler system should be designed in which the unit set pressure must be less than the maximum allowable pressure, the pressure relief valve unit and the valve shall be fitted to the connecting portion based on such a design configuration of the vacuum hot water boiler , as compared with the vacuum hot water boiler pressure hot water boiler, has its own unique advantages, table 1 Comparative characteristic of both systems were schemes.

Since our company uses WNS6-1.25-YQ split two condensing boiler, the boiler runs very stable, high degree of automation, greatly reducing the labor intensity of fireman our staff, because running very clean without any emissions, but also greatly improved our paper mill house and the surrounding environment, high operating efficiency boilers. Service is also very timely response to our technical consulting reply quickly and accurately. Especially for regular visits to thank! --customer feedback

What matters will be selected in Zigong pressure hot water boiler note of what some consumers in the choice of pressure hot water boiler, due to the skill of experience does not exist, often do not know how to start. Since particularly large series of atmospheric pressure hot water boiler, apart from differences in structure, differences in source manufacturers, should understand how many people are chosen, back to teach the public has little knowledge of some options. First, choose a good pressure hot water boiler, we must know how to construct pressure hot water boiler must be carried out on the equipment in use, installation and commissioning, inspection and maintenance must therefore be reasonable construction must be carried out normally. Second, each will have a certain pressure hot water boiler steam pressure, and for that we will have some wear and tear during use, this unit must be in the selection pressure hot water boiler series pay more attention to summary good intentions come to choose. The first three points are important in a place some pressure hot water boiler using the device, some have excellent secondary effect, can use up a good cost reduction, energy saving. So, in the days of selection pressure hot water boiler, we mentioned above must pay more attention to these matters, so that it can be like to choose a good product, good operation with good use of them. Details of the use of steam boilers should be required to guard against the use of steam boilers are becoming more common, although goods stable, safe operation. But it is not free to say manipulation. Now we come to tell you specifically tell us about some of the considerations when using steam boilers need to be wary of. First, before the boiler boot properly examine previous inspection of steam boilers boot sequence the most important thing, we should need to check where there are many, like the gas load is appropriate, whether to block the smoke pipe is already open, vacuum pumping is normal and so on .. ..... Only ensure normal boot before boiler, gas steam boilers ensure the safety of the entire security operation. Also, stop using the time to stop using the application period is the most prudent use of the sequence, the first fire to turn a small fire, then slowly extinguished, closed burner. Matters gas steam boiler safe use of which we should have so much, and if we can pay special attention to matters so much in use, it should be quite able to be safe to use gas steam boiler, to avoid generating the details of improper use.
