Waste heat recovery horizontal 1-10 ton fired steam generators utilizing shop assembled or modular field construction.

Waste heat recovery steam generator utilizing extended surface (finned tube), and non-extended tube (bare tube) designs.

Eliminating the problem of pressure test: GB150-1998 "Steel Pressure Vessel" Article 3.9 states: "to not make container pressure testing in accordance with the provisions of 3.8, the design unit should put forward measures to ensure the safe operation of the vessel, and note on drawings Ming "There are many standard deviations the user's understanding of this provision, is summarized in the need to clarify the following two questions: First, under what circumstances can relieve stress test? Second, the measures may be required after relieve the pressure test? When the catalytic cracking unit with a regenerator and a large reactor and the heat insulating layer can not withstand those based hydraulic test: in fact, only relieve pressure test performed Spot welding large pressure vessels for pressure testing the impossible, such as water by weight of the pressure vessel and the like. In other words, the reason why the pressure test exemption, because they do not have the container or a pressure test, or simply not pressure tested. In short, rather than eliminating means you can not do not do it, it is not without basis as a general pressure test in the factory production of pressure vessels. It should be noted that the pressure here means a pressure test test.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

The steam generated by the boiler is generally measured in tonnage, but the steam turbine power generation is calculated by heat, and the two can be converted: generator electric power MW = boiler tonnage × steam per ton × steam turbine efficiency × generator efficiency. The steam enthalpy depends on the parameters of the steam. The pressure and temperature of the steam are different, and the enthalpy value is also different. It is generally considered to be 0.7. The coefficient of steam turbine efficiency and generator efficiency depends on the power station unit system.
