natural circulation water tube boiler

Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water natural circulation water tube boiler is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).

Adjust the natural circulation water tube boiler combustion of coal and painting require different purpose boiler, which is the site of important product and main keywords, so the focus should be to learn and understand, but there are a lot of specific types of boilers, however, in order to allow everyone to fully learn and specifically, the following, from the boiler to proceed with this whole, rather than specific species. And hope that we can be taken seriously, so that you can give yourself a good learning. Channel and operating platform on the boiler 1. whether the relevant requirements? Channel and the like on the platform boiler, is relevant to the requirements, which is: the platform between the boiler should be connected, all the high boiler arrangement aids detection and control means, but also outside it there are pipeline valves and other needs for operation and maintenance of premises, should be set up to facilitate safe operation of platforms and escalators. In addition, the valve gear may be provided directed to the ground to operate. 2.AQC boiler and PH boiler there a difference? AQC boiler, which is a main steam boiler, PH boiler generating steam auxiliary boiler. Further, the AQC have three components boiler economizer, evaporator and superheater, PH boiler by the evaporator and superheater these two components, without this economizer member. Therefore, it can be seen from the above two points, AQC boiler and PH boiler, these two very different boiler should be proper selection and use. 3. boiler combustion regulation, what the main content? Different volatile coal, whether there are different requirements? Adjusting the combustion boiler, which is mainly adjusted to adjust the amount of fuel and air flow, is the adjustment of the air fuel ratio, which regulates purpose is to ensure an appropriate amount of fuel, needed in order to adapt to the external load, while ensuring combustion boiler It can be stable. Different volatile coal, which have different requirements, the specific terms, it is as follows: large volatile coal, high available aluminum and a phoenix once the wind speed, it is a good economic performance of the boiler; small volatility the coal should be a lower rate of primary air and primary air velocity to ensure that the ignition time of the boiler. 4. Why boiler to paint? Boilers need to use cooling towers do? Boiler painting, because the boiler is fixed line at high temperature and pressure, which has a water and salt corrosion and galvanic corrosion oxygen. Therefore, in order to avoid corrosion of boiler needs to be painted, in order to ensure and extend the life of the boiler. The boiler, which generally does not require cooling, warming is needed, therefore, it does not use cooling towers, except the power plant boiler, but the cooling tower is not used to cool the boiler.

Pressure: 0.7MPa,1.0Mpa, 1.25Mpa.(7 kg/cm2, 10kg/cm2, 12.5kg/cm2)

Type: gas fired double boiler, gas fire tube boiler( three pass gas boiler 1000kg)

Some users for a small area of ​​the natural circulation water tube boiler problem, fully condensed after the launch of commercial vertical displacement by condensing hot water boiler and hot water boiler technology upgrades premix, covers can be as low as 2 cubic meters, for the enterprise minus the boiler area is too large problem.
