than the design value of RH tube metal temperature for the concerned boiler. Commercial tools Gambit, IcemCfd and Ansys Fluent have been used for carrying out the CFD analyses and plotting tool Gnu Octave has been used to generate three dimensional surface plots. Keyword:CFD, Reheater, Super critical, Flue gas, Metal temperature, Inlet header I.
Nov 05, 2017 · To confirm this hypothesis, the steam temperatures of the PC boiler were measured using thermocouples positioned at the tube outlet in the final reheater of the crossover pass type boilers. Therefore, for the sake of data reliability, we acquired the steam temperatures from two boilers for a 500-MW power plant of the same configuration andCited by: 7
Physical processes in an inflatable furnace during the emergency operation mode of fire-tube boiler were simulated using the ANSYS Multiphysics 12.1.4 engineering software. Finite volume method and Euler method were used in conjunction with the implicit Pressure Based algorithm.
ansys on fire tube boiler - den-arend.be. CONSTRUCTION OPTIMIZATION OF HOT WATER FIRE-TUBE. TE110V was performed using FEM in ANSYS 17 program package, while a CAD model was The analyzed boiler is oil or gas fired high pressure hot water fire-tube boiler for flow temperatures up to 170 °C and permitted operating pressures of 6.0 to 12.0 bar.
General scheme of OP-650 boiler low-emission installation with the firing system is depicted in Fig. 1. 12 swirl burners are located on the front wall in two rows (6 in Burner Level 1 and 6 in Level 2).Combustion air is separated into primary, secondary and tertiary air as demonstrated in Fig. 2.Swirl vanes fixed at 45° angle are mounted in primary air-coal mixture tube to ensure burnerCited by: 14
Liquid Level Sight Gauges & Water Gauges | Boiler Supplies. A water Gauge/Gage is a device that allows you to measure the liquid level in a vessel to be Visually inspected. Water Gauges /Gages are required by ASME boiler and pressure code on steam boilers, and are also useful in many other applications such as oil in a tank. Get a Quote

Figure 1 shows a failed reheater tube from a boiler of 500 MW tur-bine. The reheater tube was of pen-dent type placed in the convective zone. The operating pressurre was 25 kg/cm2 and steam outlet tempera-ture 535"C. Flue gas temperature in the zone was 700-720°C (design). The tube material was 1.25Cr-0.5Mo (T 11 grade).[PDF]
flow pattern and overheating in some regions of super heater. Fairly high temperature values on bottom bends of tube panels are seen in conjugate heat transfer analysis. Affected tube panels are analyzed for thermo-structural stresses using Ansys under combined as well as isolated pressure and temperature effect. The stresses are found
