An air preheater (APH) is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.
Normal air preheater exist the problem of collection of ash,worn down,low temperature corrosion to effect the safe and economical operation for the boiler unit. So HTEG established the exclusive enamel research and development center to supply the complete solution and organize the scientific reserach personnel to tacle key problems and develop the new heat transfer parts-enameld tubes air preheater

Our impact sockets are available in a wide range of lengths and wall thickness and with single or double hex openings. Square openings are also available. Impact sockets are designed for use with powered impact wrenches where wrenches can be powered pneumatically (by compressed air) or electrically. The combination of wrench and impact socket can deliver greater torque to the head of a fastener. A few common types that are used are as under: 6 Point Standard Impact Sockets 6 Point Deep Impact Sockets 12 Point Standard Impact Sockets 12 Point Deep Impact Sockets 4 Point Standard 8 Point Standard Thin Wall Impact Sockets -Standard Thin Wall Impact Sockets-Deep

Brief Introduction Air preheater is the equipment that uses the boiler tail flue smoke to heat the entering air with its inside tubes .It is used to improve the heat exchange performance of the boiler, and reduce energy consumption. To adapt the different boiler burning type, different fuel and different fume ingredient, we developed the below enamel tube air preheaters to fit the different mediem: 1. The CFB boiler and coal powder boiler used enamel steel tubes, seam or seamless steel tube with green colour. 2. The rubbish burning furnace, biomass boiler used enamel steel tubes, seam or seamless steel tube with blue colour. 3. The Chain grate and layer burning boiler used enamel steel tubes, seam or seamless steel tube with brown colour. 4. The oil burning boiler, coking boiler and gas boiler used enamel steel tubes,seam or seamless steel tube with dark green. Why Choose Us? 1). Chinese famous brand 2). Competitive price with trusted quality 3). Short delivery lead time and excellent after-sale service 4). Certificate ISO9001, ISO14001, 5). We always produce good quality products with competitive price. 6). We have 50 professional engineers, 15 professional and technical teams for boiler improvement and more than 100 success cases of boiler energy-saving technological transformation.
Best price industrial boiler enamel tube air preheater with good quality is the equipment that uses the boiler tail flue smoke to heat the entering air with its inside tubes .It is used to improve the heat exchange performance of the boiler, and reduce energy consumption. 1. Best price industrial boiler enamel tube air preheater with good quality are not easily broken enamel surface, no crack, acid and alkali resistance, resistance to gas erosion, smooth and high, gas flow resistance, easy Fouling; 2. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient (enamel thickness ratio of thermal conductivity with very small, about 0.0002, the calculation is negligible), wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W; 3. Two horizontal enamel sealing tube box, the sealed tube box structure welded high strength, pipe damaged or the overall change can only block, and heat-packing seal, can only replace the damaged pipe tube, easy maintenance; 4. Best price industrial boiler enamel tube air preheater with good quality is mainly used for boiler preheater, the low temperature.
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.
