tube stringer boiler

The users who have used the tube stringer boiler all know that the hot water boiler will be corroded when it is used for a long time, which has a great influence on the service life of the boiler. So how to reduce the corrosion degree of hot water boiler? I hope the following introduction will help you. 1. The installation of exhaust apparatus in the system of hot water boiler is helpful to eliminate the air in the hot water system of hot water boiler and the gas emitted from water by heating, thus reducing the corrosion of oxygen. 2. Water supply deoxidization: when the rated power of the hot water boiler is greater than 4.2MW, the water shall be deoxygenated; the hot water boiler with the rated power less than 4.2 Oxygen should be deaerated as much as possible. 3, control the PH value of the hot water boiler water: the PH of the hot water boiler water is controlled between 10 and 12, so that a protective film can be formed on the surface of the metal to avoid the occurrence of oxygen corrosion. Corrosion problems threaten the safe operation of hot water boiler and even affect the service life of boiler. It has become an important aspect of boiler management to prevent the corrosion of hot water boiler heating surface and increase the length of boiler service. The above measures can effectively prevent and slow down the problem of oxygen corrosion on the heating surface of hot water boiler, so as to ensure the safe operation of the boiler. .

Operating costs of different fuel gas steam tube stringer boiler comparison: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.0 yuan gas / side) fuel: advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.0 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 1 yuan / kWh). Gas: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (gas prices by 1,000 yuan / ton).

2. Excellent tube stringer boiler design improves boiler efficiency, safe and reliable boiler operation, low operating cost

3. Environment-friendly big combustion chamber equipped with low emission combustion burner effectively reduce the NOx to 30mg/m3.

The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam tube stringer boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
