Product Description:

Needle shaped tube waste heat boiler is a specialized energy-saving product designed specifically for the recovery of flue gas waste heat in power generation units. By using needle shaped tubes to strengthen heat transfer elements and expand the heating surface, the heating surface on the smoke side of the water pipe is greatly increased. At the same time, strong turbulence is formed when the flue gas flows through the surface of the needle shaped tube, which improves heat transfer efficiency and reduces smoke accumulation. The waste heat recovery device has the advantages of simple structure, high thermal efficiency, long operating life, safety and reliability, and easy maintenance. At present, hundreds of gas-fired power generation units have been applied, all of which have achieved considerable economic benefits.

Product features:

1）The waste heat boiler adopts needle shaped tubes to strengthen heat transfer elements and force heat transfer, which can increase the heat transfer area by about7-8Increase the heat transfer coefficient by about times2By doubling, the heat transfer efficiency is improved by about14times

2) The waste heat boiler has the ability to self clean ash, and strong turbulence is formed when the flue gas flows through the surface of the needle shaped tube, making it difficult for the ash to accumulate on the heat exchange tube bundle

3) The waste heat boiler is wear-resistant, well sealed, and occupies a small area. The boiler body is lightweight and only comparable to conventional boilers1/2-2/3Multiple times and smaller in size, only comparable to conventional boilers1/2This ensures the convenience of boiler installation

4) The small investment in boiler foundation only accounts for the proportion of conventional boilers50%-70%, cheap price, high cost-effectiveness

5) The use of automatic control in waste heat boilers effectively reduces the labor intensity of on-site operators and reduces the number of on-site operators

6) The waste heat boiler has the advantages of simple maintenance, convenient replacement of heat exchange tube bundles, saving labor and material costs, and greatly reducing economic losses

Product advantages:

1. The waste heat boiler adopts forced circulation, that is, the steam and water working fluids inside the pipe are driven by external forces (feed water pump, hot water circulation pump). This allows for unrestricted arrangement of the heating surface and makes it very compact, resulting in good heat transfer efficiency.

2KNPTThe series needle shaped tube waste heat boiler is a specialized high-efficiency energy-saving product designed specifically for flue gas waste heat recovery. The use of needle shaped tubes with extended heating surfaces to enhance heat transfer elements as the heating surface of the waste heat boiler can greatly increase the heating surface on the smoke side of the water pipes. At the same time, strong turbulence is formed when the flue gas flows through the surface of the needle shaped tubes, which improves heat transfer efficiency and reduces the accumulation of soot. This waste heat boiler has the advantages of simple structure, high thermal efficiency, long operating life, safety and reliability, and easy maintenance.

3. Compact structure and high thermal efficiency

The heating area per unit length is large, and the needle shaped tube currently used is about the same as a light tube7.8Twice, about the size of a spiral finned tube1.3Double, all butt welds are welded using argon arc welding, which greatly improves the welding quality compared to manual welding; The volume and weight of the equipment have been significantly reduced, resulting in a significant decrease in equipment investment for the same heat exchange area. This provides users with ample space for equipment layout and installation.

4. Seismic resistance and noise reduction

Due to the structural design of the equipment and the inherent characteristics of the needle shaped tube, it has the structural features of a muffler, thus the equipment can function as a muffler.

5. Easy to install, use, and maintain

When installing the equipment, simply connect it to the exhaust outlet of the smelting furnace, and the equipment can be put into normal operation; The waste heat boiler is equipped with an inspection door, which can determine the cleaning cycle according to the actual situation, ensure the heat exchange effect, and increase the service life.
