Basic Information

Place of Origin Jiangsu China (Mainland)
Air preheater, or boiler 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 preheater. 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;
