heat exchanger

The machine is made up of some heat pipes,can tranform the heat collected from the flue gas into three state.

  The character of heat pipe heat exchanger:structure simple, high-efficiency heat exchange; small pressure loss; safe and reliable; flexible mix tempreture.  The type and structure of Heat pipe heat exchanger :according to the state of the hot and cold fluid flow, heat pipe heat exchanger can be divided into gas - gas, gas liquid,liquid - gas; from the structure  of the heat pipe heat exchanger , it can be divided into the overall style,  separated style ,circumqyrate style and combined style.

(A)  the heat pipe air preheater Applications: to absorb heat from flue gas, heating air for combustion to reduce fuel consumption and improve the combustion condition in order to achieve the purpose of energy conservation; can absorb heat from flue gas for heating gas in other media, such as coal gas.

Equipment advantages: * Because of a gas - gas heat exchanger, can be used on both sides of the fin-tube, heat transfer efficiency for 5-8 times comparing with the general air preheater; * Because the flue gas exchange heat ouside the tube,so it is conducive to clean ash; * Because each heat pipe is independent of the others,so it is convenience to strip, and allow the expansion of freedom; * After design,it can adjust wall temperature,dew point corrosion will be avoided. Structure: There are two common types of structures, namely: heat pipe-placed vertically, gas and the air flow reversed, see Figure 1; heat pipe-placed tilted, gas and the air flow reversed vertically from top to bottom.

(B) the heat pipe economizer   Applications: to absorb heat from flue gas for heating water, the heated water boiler can return to the boiler (as economizer), can also be used alone (as a water heater) to improve energy efficiency, energy saving achieved. Equipment advantages: * For the side of the fin-tube gas, water for the side lights, high heat transfer efficiency; * Reasonably designed to enhance the wall temperature, dew point to avoid corrosion; * Effectively prevent wall damage caused by the mixing of hot and cold fluids;

Structure: Based on the water side of the heating of the way, there are two common types of structure: the overall heat-tank (heat pipe used to place vertical) and water-heating convection sets (the use of heat pipe inclined to place)

 (C) of the heat pipe waste heat boiler Applications: as a heat pipe heat transfer components, to absorb the higher temperature of the gas used to generate steam heat, steam can be produced by Bing and steam into the network (subject to pressure from piping), can also be used for power generation (steam than And a stable heat source large) or for other purposes. On the steel, petrochemical plants and industrial furnace, which is a popular form of waste heat recovery.

Equipment advantages: Each heat pipe heat transfer is an independent unit, according to different levels of temperature and design; * Based on the need to easily choose the demolition of the structure of the heat pipe, so that the installation and maintenance easier; * The complete isolation of the heat pipe heat and cold source, will not have a mixing of hot and cold fluids; * Side of the flue gas for heat exchanger tube, easy to ash. Structure: There are two types of structures, and see a map b. Figure drum for a direct-boiling, that is, the heat pipe cooling of the paragraph directly into the drum, so that the inner drum of boiling water; plans for the b-boiling inside the casing, that is, the heat pipe cooling section of casing was surrounded by water, Casing so that water flows in a state of boiling, steam generated by the re-import the drum.
