过去几年中,锅炉制造业的发展处于稳定状态,主要的精力集中在汽水系统的改进。气密封焊接水冷壁已是新型锅炉的常用结构形式,其运行和制造技术问题亦应认为已获得解决。进一步改进汽水系统的可能性已经用尽,因此没有必要再在这一领域里浪费科研和生产费用。 Over the past few years, the boiler manufacturing industry has been in a steady state of development with a major focus on the improvement of the soda system. Gas seal welding water wall is a common structure of the new boiler structure, its operation and manufacturing technology should also be considered to have been resolved. There is no need to waste research and production costs in this area because the possibility of further refinement of the system has been exhausted.
