flame smoke tube boiler
To the steam flame smoke tube boiler blowdown installed on the heat exchanger or boiler blowdown recycle, and subjected to rigorous controls to ensure emissions below 5%, and if the best conditions to control below 2%. In addition, heat may also be recovered by utilizing a trap device expansion, so that the work holder can also trap properly. Trap in the steam condensate, water quality is often good, it comes from the quality of the boiler feed water, the recovery process can also save the cost of water. Fourth, always check the boiler pipes and various valves.
Henan gas flame smoke tube boiler disabled corrosion prevention, mitigation methods in order to prevent or mitigate disabled corrosion protection measures should be adopted shutdown. Many Henan method gas boiler shutdown protection, mainly divided into two categories: wet and dry protection protection. Wet disable protection commonly used in the short time, for example within one month. Wet protection common method is to fill in the other peroxygen Henan gas boiler water or aqueous alkali, the holding pressure 0.3 ~ 0.5Mpa, to prevent air from leaking into the. If a longer shutdown, or cold weather, in order to prevent freezing equipment, should be protected by a dry method. After shutdown method, the temperature dropped to 70 ~ 80 ℃, the furnace was let go all the water, using waste heat of the gas boiler Henan the water in the heating surface all evaporated to dryness, and dried with compressed air without water vapor furnace all blown off, and then placed in the container-contained anhydrous calcium chloride to the drum. Per cubic meter of water volume ratio 0.5 ~ 1.0L of calcium chloride was placed (e.g., with lime according to 2kg / m3 basis), then the manhole is closed, periodically checked and found to be replaced when the desiccant into powder. Henan gas boiler can also be charged to charge ammonia or nitrogen is protected, its preparation and use as a desiccant. Since ammonia is lighter than air, so protection during charging and ammonia, the ammonia gas should enter the upper exhaust air from the lower portion. Nitrogen is slightly lighter than air, can enter the upper portion of nitrogen from the exhaust air from the lower portion. To prevent air from leaking into, the pressure should be maintained to 0.3 ~ 0.5Mpa, the pressure should be reduced to replenish ammonia or nitrogen.
Coal consumption and coal-fired steam flame smoke tube boilers of some commonly used models: For this kind of boiler coal-fired steam boilers, because it is one of the website product, so it should be familiar with and understand, at least, can not be ignorant. Therefore, based on the above requirements, the following will be immediately proceed to leave you inspired and in some gains, and at the same time, also can add some expertise. 1.8t / h coal-fired steam boiler, its coal consumption per hour, how much is? 8t / h coal-fired steam boilers, coal per hour which, in general, can be calculated, and the specific calculation thereof, are as follows: 1 ton coal-fired steam boiler, the required amount of heat is 600,000 kcal / hour, taking into account the calorific value of the two types of bituminous coal, and thermal efficiency of the boiler, which is about 75%. Then, based on these data, it can be concluded that the coal-fired steam boiler, which is the amount of coal per hour for 145.5kg.
ASME is referred to as "the American Society of Mechanical Engineers", mainly dedicated to the development of machinery industry standards, and was recognized by most countries in the world. Get ASME certification is fast flame smoke tube boiler and pressure vessel products to the international market, the only way to obtain a certificate issued by ASME and stamp means getting the products exported to international market, "pass."
