Two Sets 420TPH Natural Gas Boiler in Northeast China

Taishan Boiler

Natural Gas Boiler is the most common fossil fuel boiler in recent years around the world. Gas power plant boiler manufacturer Taishan Group won 2×80MW gas cogeneration project, covering two sets 420t/h high pressure gas fired boilers.

This 2×80MW project has a total investment of 130 million USD, covering an area of 104,300 square meters. Two sets 420t/h high-temperature and high-pressure gas steam boilers with two sets 80MW back-pressure steam turbine and generator sets. The project will start to operate and connect to the grid at the end of December 2021. Each year it will consume 300 million cubic meters natural gas and increase heating capacity by 12 million square meters.

We are responsible for the design, production and assembly of 420t/h high-temperature and high-pressure natural gas boiler. This is another milestone after 12 years of friendly cooperation with Jieneng Thermal Power. This strategic cooperation is another fruitful result towards “large tonnage, large capacity and large customer” model. In the next step, Taishan Group will optimize design plan, accelerate production progress, ensure product quality, and control pollutant emission.
