explanation

HINO-TEC plate heat exchangers are designed to exchange heat between dust-free gases. They are made by joining two pressed plates together and welding them to create a completely airtight structure. They have a wide range of applications, including exhaust heat recovery from industrial furnaces, and are widely used for air preheating in deodorizing equipment, food drying, boilers, paint drying, and more.

• 

  It contributes to energy savings by preheating combustion air from exhaust gases at a maximum temperature of 850°C.

• 

  For small flow rates, it can be made smaller to save space.

• 

  Installing a cleaning nozzle may help prevent dust blockage.

• 

  This is a visual measure to prevent the air coming out of factory chimneys from turning into white smoke.

Design Example

explanation

The square corrugated tube heat exchanger is designed to exchange heat between gases containing dust (gas and gas).By using a tube (corrugated) that is made by processing a straight (bare) tube into a spiral shape, the flow velocity inside the tube can be increased, resulting in improved heat exchange efficiency compared to bare tubes.

explanation

Since rectangular corrugated tube heat exchangers are designed to exchange heat between gases containing dust (gases), dust blockages inside the pipes can be a concern. In such cases, dust adhesion prevention devices are effective. A chain hanging from a shaft is inserted into the pipe and moves mechanically to prevent dust from adhering inside the pipe. These devices are mainly used in clean centers around the country.

• 

  The tube appears to be penetrating.

explanation

Shell and tube heat exchangers are designed to recover heat from gas to gas or gas to water. Because the shell (body) is cylindrical, it can also handle high pressures. We have a track record of designing and manufacturing in accordance with pressure vessel structural standards.
Large-sized units are increasingly being used in sewage sludge incineration facilities.

• 

  Corrugated tubes are used for the heat transfer tubes. We have experience in manufacturing large shell diameters up to φ2000mm.

• 

  Used for small flow rates. As it is a standard device, it offers advantages in terms of cost and delivery time.

explanation

Steam air heaters (SAH) that use steam to preheat air (gas) often use the bare tube type, which preheats the air in a garbage pit using superheated steam or saturated steam.
Hot water generators that can produce high-temperature water of less than 100°C by using high-temperature air (exhaust heat) include the plate fin tube type and the strong high-frequency welded fin tube type.

• 

  It is used in waste incineration power plants, etc. It can preheat air using high-pressure superheated steam. It has a proven track record as a product that complies with pressure vessel construction standards.

• 

  By using fin tubes, which have a large surface area, the unit can be made more compact.

• 

  Welded fins are used when the heat source is very hot. They are larger than plate fins but offer greater strength.

explanation

Also known as the radiation type or two-cylinder type. This method is suitable for recovering relatively high-temperature heat from gases containing high concentrations of dust. When CO2 and H2O components are present in the high-temperature heat-releasing gas, infrared radiation is emitted from the gas, and this radiation transfers the heat from the gas to the heat transfer surface. This means that less high-temperature gas fluid is required than usual, there is little pressure loss on the gas side, and there is no need to worry about dust clogging.
