package boiler water tube type

What are the characteristics of the gas package boiler water tube type gas boiler itself also has a lot of performance highlights, gas boilers have been many updates in accordance with the law of a user operation in quality manufacturing process. It may be best to use and easy to supply the user. Continued after the Let's see what are the features of a gas boiler. First, a high level of wisdom wisdom of their high level of gas boilers, based on the user's operating instructions to implement electronic ignition and stopped running, etc. Since independence, particularly in the safe and stable operation, also achieved not on fire prevention failure device to reduce the hidden dangers arise. Second, the modest framework to achieve non-flammable gas interference film, can improve the heat, reduce the heat loss is very large, users are more modest framework of natural gas, and users are also particularly easy when in operation, does not require the use of someone with care, save time and more effort. In summary highlights some of the details of the gas boiler, after more than talking about is not what we are and such facilities also have more thought. When selected after heating facilities, but also to think more about it.

The method of starting the package boiler water tube type during boiler startup control drum wall temperature difference of the process to be controlled in a predetermined drum wall temperature difference may take the following measures within 40 ℃: (1) water temperature before ignition can not be too high, not too fast speed, according to rules of execution. (2) water is completed, the bottom may be put into steam heating conditions. (3) strictly control the raising rate, in particular 0 ~ 0.981MPa boosting speed stage should be less than 0.014MPa / min. Rate of temperature rise not greater than 1.5 ~ 2 ℃ / min. (4) should be regularly switching angle oil gun, until the next row when four full cast oil gun, each part as far as possible evenly heated. (5) via the above-described operation can not effectively control the drum, the lower wall temperature, then when the approach or reach 40 ℃ booster should be suspended, and the sewage regularly, in order to enhance the circulating water, and stabilized until the temperature difference is less than 40 ℃ line boost.

In recent years, the increasing popularity of Yichun City, Jiangxi Province comprehensive energy saving coal-fired package boiler water tube type upgrade project, plans to eliminate 75% of the downtown 10 steam tons / hour and below the coal-fired boilers, a ban on new 20 tons of steam / hour and less fuel coal boilers; the rest of principle, then the new 10 steam tons / hour of coal-fired boilers.

Following this, Jiangxi Province Department of Finance issued a special subsidy fund boilers, Yichun downtown 2015--2016 phase-out 10 steam tons / hour coal-fired boilers companies grant. The subsidy standard is: 2 out of steam tons / hour and coal-fired boilers, subsidies to 10,000 yuan / Taiwan; out of steam 2-10 t / h coal-fired boiler, subsidies for 20,000 yuan / Taiwan.

After the scale appears, the thermal conductivity is only 0.5% of the metal. After the package boiler water tube type scale appears, if the heat efficiency of the scale is reached, the temperature of the heating surface inside the boiler can only be increased. For example, when the wall temperature is 250 °C, When the scale is 1mm, if the same thermal effect is to be achieved, the wall temperature will increase to 650 ° C. At this time, the heat absorption rate is extremely low, the energy consumption is increased, and the fuel cost is doubled.
