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.
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 The purpose of the boiler heat exchanger parts air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance system and the flue gas stack. It also allows control over the temperature of gases leaving the stack (to meet emissions regulations, for example). Advantages of our product GB3274 enameled tube air preheater a).Improve and strengthen the combustion when crosses air preheater then enters the furnace, accelerates the fuel drying,the ignition and combustion process, ensures stable combustion in the furnace, and it is good for improving, strengthening the combustion effect. b). strengthen heat transfer due to improved and intensified combustion furnance and the hot air temperature in the furnace is improved, the average temperature level in the furnace is improved, thereby strengthening the furnace radiation heat transfer.
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.
