China supplier boiler hot selling

Recently, the Longhai carried out safety campaigns to the china supplier boiler hot selling, the campaigns start from the four directions, whether units in accordance with the boiler 'boiler safety practices "to use the correct boiler conducted a comprehensive inspection.

First, the unit register in a boiler boiler inspection. The use of units to crack down on unauthorized use of untested or failed the inspection of boilers.

Second, the units are equipped with a boiler if the security officer and fireman personnel. Focus on checking whether the use of units as required "special equipment operator assessment rules," the fireman with security personnel and staff to meet the requirements, and whether the person has made fireman fireman card.

Third, in the boiler unit will be the safety management system, emergency plans to check the system; and to convey the importance of this inspection in the boiler unit, raise awareness of security units.

Fourth, strengthen supervision of energy-efficient boilers, boiler and actively promote energy efficiency testing, at present, boiler energy efficiency testing has been completed a total of 112 units.

To date, the Longhai inspection operations were dispatched inspectors 209 passengers, checked boiler unit 136, check the boiler 168 units, eliminate safety hazards at 9, and urge the use of sealed units to enhance the energy efficiency of boilers 21 units.

And with the Commission by letter, and environmental protection departments to further promote the comprehensive upgrade of coal-fired boiler energy saving project, disable the coal-fired boiler 53 units, 34 units scrapped, replaced by raw material boiler fuel and natural gas fuel of a total of 40 units, is out of the city coal-fired boilers to make a positive response.

Early-generation CFB technology emerged in the late 1970s and early 1980s as bubbling fluidized bed technology using the same china supplier boiler hot selling floor grid as circulating designs. Ash or river sand was introduced to create a fluidized media that produced an active thermal zone within the first 15 feet of the combustor floor. But the media did not circulate out of the boiler and back into it for re-burning.

In production, there are often some thorny problems in china supplier boiler hot selling 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.

If the customer is replaced by a new one, the steam china supplier boiler hot selling of the same tonnage can be directly considered. But more is the need to meet the actual needs of customers to choose the right size of the boiler. Customers can choose the boiler that meets the maximum demand according to the steam demand of the textile mill and the demand of different time periods and different periods. The determination of boiler fuel needs to take into account factors such as boiler fuel consumption, fuel price, and environmental policy.
