15 Ton Natural Gas Boiler Introduction
Yili Group, the largest dairy company in China, invested in a green production and intelligent manufacturing demonstration application project in Wuwei, Gansu. The 15 ton natural gas boiler purchased for this project is mainly to meet the heat and heating demand for production in winter. According to the project requirements, the boilers use natural gas as fuel, so ZOZEN Boiler recommends the WNS series. WNS series gas-fired steam boiler have sufficient storage space and heating surface, large furnace volume, good steam quality, sufficient power output and low water content. At the same time, the boiler selects advanced low-NOx burner to ensure full combustion of natural gas and effectively reduce NOx emission. In addition, this series boiler adopts advanced condensing technology to recover the waste heat in flue gas, raise the inlet water temperature and lower the exhaust smoke temperature, so that the thermal efficiency can be increased to over 98%.
The natural gas steam boiler is mainly composed of two major parts: the shell and the furnace, and has accessories, instrumentation equipment, automatic control and protection systems to ensure its safe and economic continuous operation. The principle of natural gas boiler is reasonable. The boiler is a boiler steam package with a water-cooled wall. There are two smoke return tubes on the left and right sides of the drum, and the front smoke box is folded back at the front of the drum. There are descending tubes and water-cooled wall tubes between the drum and the lower box, which form the framework of the combustion chamber. There is a vapor separator at the top of the steam ladle to reduce the water carried out by the steam. The heated surfaces of the pot are the lower part of the drum, the water-cooled wall pipe and the smoke and fire pipe.
Customer feedback
At present, the 15 ton natural gas boiler is officially put into operation. During operation, it was found that the boiler emissions were lower than the local emission standards, and the energy saving and emission reduction were effective and met the environmental protection requirements.During the installation, the natural gas steam boiler is reasonably designed, with a larger boiler chamber and low burner emissions, with NOx as low as 30mg/Nm3. The gas steam boiler flue and boiler flue gas outlet use internal insulation measures, effectively reducing the noise in the boiler operation. The combustion chamber adopts full-film water-cooled wall structure and adopts micro positive pressure combustion, no smoke problem and no pollution in the operating environment.
