Specifications

Air preheater, or boiler preheater, heat pipe air preheater, is an important boiler part. Heat pipe air preheater.

Air preheater, or boiler preheater, heat pipe air preheater, is an important boiler part. It can be divided into two kinds, Tubular type air preheater and Vertical type air preheater. Air preheater pipe type, mainly using industrial furnaces or smoke waste heat boiler combustion air preheating furnace enter, such not only improves the thermal efficiency of the stove and reduce the environment pollution. Due to the gas - gas combustion on both sides of the heat exchanger, in order to strengthen small coefficient of heat transfer, usually installs the fin-root on both sides. Typical of the air preheater, its shape is commonly, main components for vascular cuboid, shell and partition.

The tube evaporator and condenser separated by partition. Clapboard, shell and tube bundle was composed of the thermal fluid flow, cold. Heat up part of clapboard bundles, its main effect is sealed to prevent the flow, two fluid infiltration. The heat pipe for 5-30 general coefficient. In order to prevent the flue dust jam, smoke greatly; lateral fins spacing The air in the air cleaner, to obtain higher rib, the coefficient of finned spacing advisable. Heat pipe bundle general layout, such as column can make heat coefficient increase. Heat pipe bundle installation position have vertical and horizontal and three tilt. The advent of gravity heat, widely used in the air preheater pipe, but must be tilted or vertical layout, and the only for heating section. Heat air preheater and general air preheater, because both sides gas can be easily realized, thus greatly strengthened side the heat transfer process. Then will the traditional gas - the air flow pattern to pure countercurrent cross, improving the heat transfer model of logarithmic mean temperature, pressure. In addition to the side of the gas tube can flow into the prey, but around the side of the average heat coefficient increased by 30%. Based on the above several reasons, air preheater pipe heat transfer coefficient than normal tubular air preheaters.

Product advantage:

1.High corrossion resistance proerty;

2.Small covering area;

3.Pipe and tube plate in every link between separated, the heated bilges cold heat distortion is not bound to avoid stress destruction;

4.Single pipe, tube single or parts of equipment failure does not affect the heat normal operation.

Two fluid were heat tube, can go outside fin;

Product Culture

Chase: a strong brand, a adhere to the faith, adhere to the principle of a sentence.
     Thirty-two years of history tells us, can ensure that we continue to move forward is to develop new technologies and tough, on the quality of the product to customers, commitment to commitment.
     2008, the development of the global economy suffered, China also experienced this change, and as a production enterprise new JPMorgan Chase, also suffered from the crisis spread. The economizer market share decline, many enterprises fall in this field changes. And we, with our strong belief, strive to maintain, smiling face: production, we do not price cuts and change the quality of the products; marketing, we do not win a share to speculation; service, we do not reduce the sincerity is a little small profits......
    In recent years, the export reduction, makes some over the pursuit of profits, in order to short time to reverse the development dilemma, not professional in product casting adulteration:
    They use scrap iron and sand mixture in casting weight, we insist on the use of gray cast iron;
      They in weight but never reach the standards, and our products undergo strict quality testing;
      They are cast in that wall thinning to reduce costs, but we always insist casting process;
      The weight of the adulterated, is to denigrate the customers trust; substandard products, is a dereliction of duty for their technology; we have no intention to expose the industry insider, just as a good reminder: wall thin products, easy to crack, fragile, explosive. The export of such products, cracks in transit, without the timely detection of installation, may lead to dire consequences, the pressure is not standard, products will be subjected to high pressure in use, once the explosion, will bring a terrible economic losses and casualties for you.
    Thirty-two years, we always do one thing at a time.
    Thirty-two years, we the persistence oneself responsibility.
    Since 2008, we have on the quality of the products adhere to, and partners together through this crisis, today, our export share increased steadily. Strict product quality, for us to win the praise of many overseas customers. Here, we thank the trust of partners.
    If later, there is such a crisis, we would like to work with you in the face. Of course, we sincerely hope it doesn't happen again. So, maybe we can sit down, drink a cup of coffee, to talk about life, talk about life. Of course, your products, please rest assured.
