| Abstract: | There are some common problems existing in the design of the submerged tube heating device.Such as the high energy consumption,low thermal efficiency and the heat power being unable to reach the production request.These problems result from the thermal equilibrium computational complexity.Based on these problems the author has compiled the computer simulation procedure for the design of the submerged tube heating divice,making use of relevant physical parameters and classical formulas of combustion and heat transfer.Practice shows that the results of the simulation procedure and the experiment are identical.The simulation procedure makes it facilitate to select the best scheme. |
