ZOZEN Boiler Develops Various of Flue Gas Heat Recovery Technologies

The price of natural gas is far higher than that of coal, enterprises are facing the problem of high cost. ZOZEN Boiler develops and designs a variety of gas boiler flue gas waste heat utilization technologies to effectively improve the thermal efficiency of the boiler system.

ZOZEN energy-saving gas-fired boiler has high thermal efficiency and wide market application

ZOZEN Boiler creates several energy-saving gas-fired boiler system

The energy-saving effect of gas-fired boiler is not only related to combustion efficiency and thermal insulation effect, but also closely related to the heat loss of exhaust gas. When the heat energy of boiler fuel combustion is not fully absorbed, part of the heat energy is discharged with flue gas, resulting in a large amount of heat energy loss.

In order to make full use of the exhaust gas temperature, the technical personnel of ZOZEN Boiler innovatively designed a variety of energy-saving gas-fired boiler systems, such as condensation type, air preheating type and waste heat boiler type to meet the different needs of users under different working conditions. According to the energy efficiency test, the thermal efficiency of ZOZEN energy-saving gas-fired boiler is up to more than 98%.

At the same time, the gas-fired boiler is equipped with advanced boiler control system, with the control alarm and interlocking devices of water level, steam and pressure, to ensure the safety of boiler operation.

ZOZEN WNS series gas-fired boiler with air preheater is especially suitable for a compact boiler room

Recently, in the boiler room reconstruction project of Amperex Technology Limited (ATL), ZOZEN Boiler has reached cooperation with ATL again by virtue of the flue gas heat recovery technology of gas-fired boiler. ZOZEN Boiler customized the WNS series air preheating gas-fired boiler for ATL.

ZOZEN customized gas-fired boiler

The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.

The energy-saving gas-fired boiler is particularly suitable for users with compact boiler room area. ZOZEN technician optimizes the overall structure and arranges the air preheater on the top of the furnace; the air duct adopts hidden design and is integrated with the boiler body, which not only improves the thermal efficiency of the boiler, but also greatly reduces the occupied area of the boiler system, making the layout of the boiler room more reasonable.
