Application area Engineering generalcontractor Boiler modification Equipment installation

Application area

Shanghai industrial boilers provide a one to one solution for different industry attributes and needs of customer enterprises.

Engineering generalcontractor

Shanghai industrial boiler is also committed to providing customers with energy conservation and environmental protection boiler project package solution.

Power station boiler EPC package
Shanxi Gaoyi Iron and Steel Co., Ltd. 15MW high temperature and extra high pressure gas power generation project

Unit operation mode:

A 190t/h high-temperature ultra-high pressure gas boiler (blast furnace gas mixed with converter gas) +1 15MW high-temperature ultra-high pressure back pressure steam turbine unit, steam turbine back pressure parameters: 3.9MPa (a), ~ 373 °C. The back pressure of the steam turbine is returned to the boiler reheater, and the steam temperature is raised to 450 ° C and sent to the steam blower of the steel mill.

Fuel fuel:Mixed gas of blast furnace gas and converter gas

Ignition method:Liquefied gas ignition

In principle, the boiler operates at base load, but has variable load peaking capability. The boiler has good adaptability to the sliding pressure operation and the constant pressure operation.

The time from ignition to full load of the boiler meets the following requirements under normal starting conditions:

Cold start (stop more than 72h)6~8 hours

Warm start (stop 10-72h)3~4 hours

Hot start (within 10 hours of shutdown)1.5~2 hours

Temperature adjustment method:The superheated steam is cooled by two-stage water spray; the reheated steam is cooled by a small amount of water spray.

The service life of the boiler is 30 years, and the life of the convective heating surface flushed by the smoke is more than 120,000 hours. The overhaul interval is 5 years.

The project has been put into operation according to the installation, and all the indicators have reached the predetermined requirements.

Boiler modification

Shanghai industrial boilers can be retrofitted by assembling a Seiko retrofitting team, which can be customized according to customer requirements according to local conditions.

With the continuous improvement of national energy policy and environmental protection requirements, Shanghai Industrial Boiler Co., Ltd. and Shanghai Industrial Boiler (Wuxi) Co., Ltd. have carried out in-depth research and development on the transformation of coal-fired boilers.

High parameter transformation
For example, the secondary high pressure (5.3MPa) is changed to high pressure (9.8MPa...
Coal to gas reform
For example, a circulating fluidized bed/pulverized coal fired boiler is converted in...
Environmentally friendly low nitrogen transformation
The FCB coal-fired boiler will be retrofitted with a low-nitrogen combustion system. ...
Expansion and transformation
For example, a 35t/h boiler is expanded to a 50t/h boiler....
Combustion efficiency transformation
For example, the inefficient chain furnace grate boiler is transformed into a highly ...

Shanghai Industrial Boiler Co., Ltd. and Shanghai Industrial Boiler (Wuxi) Co., Ltd. are willing to customize various boiler renovation solutions for the majority of users.
In order to improve the performance of the original boiler and reduce the emission concentration of the boiler, for the country's energy-saving and environmental protection cause to make due contributions.

Equipment installation

The quality of the engineering installation directly determines its effect after being put into use.
