EXPERIMENTAL AND SIMULATION STUDY ON THE EFFECTS OF TUBE COIL PLATES ON THE PERFORMANCE OF STEAM PACKAGED BOILER

Enhancement of heat transfer intensity in thermo technical apparatus especially boiler is a great significance for industry. Besides the savings of primary energy by increase the boiler efficiency, it is also led to a reduction in size and weight. The performance of the boiler is depend on how efficient is the rate of heat exported by the fluid to the heat being supplied by the fuel. Therefore the improvement of heat transfer across the boiler tube contributes greatly to the boiler efficiency.
The rate of heat transfer to the water depends on heat combustion temperature, operating pressure, total surface area of the coils as well as the material of the coils inside the tubes. However, coil plate is one of the most important members of enhancement technique which is employed extensively in heat exchangers.
Based on the experimental and simulation result, it is proven that the tube coil plates will increase the performance of the boiler by disrupting the fire flow from laminar to turbulence flow thus reducing the speed and allowing more heat transfer across the tube.
