Gas-fired Superheated Steam Boiler for Distributed Energy System Project

The distributed energy system project built by the customer company provided electric energy and heat energy for the surrounding enterprises through the cogeneration unit of gas-steam combined cycle.

Before the implementation of the project, the surrounding enterprises were mainly self-built small boilers for decentralized heating, and did not realize centralized heating. Therefore, the project plans to purchase several sets of gas-fired steam boilers to meet the central heating needs of surrounding enterprises. As a distributed energy system project, customers put forward higher environmental protection standards and technical requirements for the gas-fired steam boiler, so as to realize power generation with steam turbine and provide electric power for enterprises.

Rated steam capacity: 8 tph, 20 tph

Rated steam pressure: 1.25 MPa ,3.2Mpa

Fuel design: Nature gas, coke oven gas, blast furnace gas, carbon black off-gas, biogas, LPG, diesel, heavy oil, light oil, crude oil, etc.

Rated steam temperature(°C): 194-540 °C

ZOZEN Boiler has customized a technical scheme for the project, including 3 sets of SZS series gas-fired superheated steam boilers and 1 set of WNS series gas-fired superheated steam boiler, of which two medium-temperature and medium-pressure SZS series gas-fired superheated steam boilers are used to cooperate with steam turbine for power generation.The overall energy-saving effect of ZOZEN gas-fired superheated steam boiler is remarkable, and the thermal efficiency is up to more than 98%. The design of the large volume of the furnace ensures the sufficient burning, and the steam temperature can be increased to 270°C through the superheater, so as to meet the requirements of power generation and heat supply. Meanwhile, in order to meet the local environmental standard, ZOZEN gas-fired boiler adopts advanced low-NOx combustion technology and imported burner, which can control the emission of nitrogen oxides within 30mg/Nm3 and meet the ultra-low nitrogen emission standard.

To meet our needs in heating and power supply, the ZOZEN engineers closely communicated with us and provided scientific and detailed design scheme. The superheated steam boilers with different parameters solved the energy consumption problem practically. ZOZEN Boiler was a trustworthy partner.
