new type high quality steam boiler

In production, there are often some thorny problems in boiler operation. Needless to say, the editor for you to sort out the boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. In the process of manufacture, transportation, installation and maintenance of boiler, it is inevitable that some impurities such as dirt, iron chips, welding slag, iron oxide and so on will be produced and glued to the pressure parts of the steam and water system in the process of manufacture, transportation, installation and maintenance. As soon as these impurities enter the steam-water system in operation, they will do great harm to the boilers and steam turbines. Therefore, the boilers before they are installed and overhauled must be chemically cleaned to remove them. Feed-in speed of boiler before start-up Degrees should not be too fast, generally no less than 4 hours in winter, other seasons 2 to 3 hours, especially in the initial stage of water should be slow. The inlet water temperature of a cold boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. If the boiler is not fully cooled, the inlet water temperature can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. The reason is! (1) because the drum wall is thicker and the expansion is slow, the tube wall connected to the drum wall is thinner and the expansion is faster. If the inlet temperature is too high or the inlet speed is too fast, it will cause unevenness of expansion, crack of welding joint and damage of equipment. (2) when water supply enters When the drum is in contact with the lower wall of the drum, if the difference between the feed temperature and the wall temperature of the drum is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls of the drum will produce a larger expansion difference, resulting in a larger additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. When the temperature of the heated surface is lower than the dew point of the flue gas, when the temperature of the heating surface is lower than the dew point of the flue gas, the steam in the flue gas is combined with the SO2,SO2 to form the sulphuric acid steam, which condenses on the heated surface. The boiler always causes low temperature corrosion of the heating surface first. The cold end of air preheater is prone to low temperature corrosion.

After gas boiler in place, the installation can proceed to the matters specific installation process is as follows:

1, the valve is installed

State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback

Three significance of using condensing Boiler

Condensing boiler, as a kind of necessary equipment used by many enterprises, has been favored and respected by users because of its outstanding advantages such as advanced condensation replacement technology, intelligent control mode and high energy efficiency in the production process. Equipment supplied by condensing boiler manufacturers in stock has become increasingly popular in recent years, because users not only see the advantages of their equipment, but also become more aware of the significance of using condensing boilers. In particular, they are reflected in the following three levels:

1. For enterprises to improve energy efficiency condensing boilers because of the use of domestic leading all-condensing heat transfer technology, the use of all-imported accessories in the equipment, while maximizing the benefits for enterprises, but also improve energy efficiency, using pure imported parts and components. Its quality is more guaranteed, and the rate of return repair is lower, so it saves a lot of maintenance cost and reduces the failure rate of equipment.

2. Energy-saving and emission reduction, and for the benefit of the society, condensing boiler equipment is increasingly recognized by enterprises and government departments because of its good energy-saving and emission-reducing effects. With the increasingly serious global air pollution, the country pays more attention to environmental protection indicators. The emergence of condensing boilers has solved this problem for the society for enterprises. With its continuous application and popularization, air pollution can be effectively alleviated, and it is also of great positive significance to human beings.

3, conducive to the continuous innovation of boiler industry condensing boiler use scope gradually expanded, in order to meet the different individual needs of more users, condensing equipment manufacturers must increase research and development efforts, Continuous reform and innovation to introduce more competitive advantage of new products to meet the rigid needs of the market.

High Efficiency Steam Boiler? Heating Help: The Wall

Stack Temperature It really boils down to stack temperature. (Pun intended.) It's conservation of energy. Whatever heat goes up the stack doesn't go into the heated space, A high efficiency furnace or boiler sends it's combustion products out at less than 200 F, but even an "efficient" steam boiler might have a stack temperature of 300 F or more.
