What are the components of natural gas boiler?

In recent years, due to the increasingly strict environmental protection policy, natural gas boilers have emerged as the times require, and are favored by the majority of enterprises for their high efficiency and environmental protection. Many people don't know what the components of natural gas boilers are, and they are often blind when designing schemes. Taking the common WNS and SZS natural gas boilers as examples, this article introduces the components of natural gas boilers.

Components of natural gas boiler

The natural gas heating of boiler is not a single device, which is precisely composed of boiler body and boiler auxiliary equipment. The auxiliary equipment is mainly composed of burner, chimney, sub-cylinder, feed water pump, electric control cabinet, water treatment and valve instruments. Specific components of natural gas boiler are as follows:

1. Boiler body of the natural gas boiler

WNS and SZS series gas-fired boilers adopt large furnace design, which provides sufficient space for fuel combustion. WNS gas boiler has compact structure, stable and reliable operation, and is equipped with boiler water level and steam pressure control, alarm and interlock to ensure the safe and reliable operation of the boiler. WNS series natural gas boilers are composed of large-diameter corrugated liners and high-efficiency threaded flue pipes, which improve the heating surface of the boiler. With the energy-saving device at the end of the flue, not only the smoke exhaust loss is reduced, but also the thermal efficiency of the boiler is as high as 98%, helping customers achieve the goal of energy saving and emission reduction.

2. Combustion system of the natural gas boiler

According to the fuel used, the corresponding burner and fuel supply system are configured. In general, the boiler uses a blower for micro-positive pressure combustion, and in special cases, an induced draft fan needs to be added for balanced ventilation. ZOZEN gas-fired boiler is equipped with advanced burners, with automatic purging, electronic auto-ignition, automatic combustion, automatic proportion adjustment of wind, oil (gas), safe and stable performance and good combustion effect.

3. The heating surface of the natural gas boiler

ZOZEN’s boiler meets the actual working conditions and requirements, and will be equipped with energy-saving equipment at the tail of natural gas boiler, such as economizer, condenser and air preheater, which can effectively reduce the exhaust gas temperature and improve the thermal efficiency of the boiler.

4. The steam water system of the natural gas boiler

It is composed of boiler body, tail energy-saving equipment, water treatment device, feed water pump, air cylinder and other equipment. After passing through the water treatment device, boiler feed water enters the boiler, and then enters the steam or hot water pipeline after being heated.

5. Control system of the natural gas boiler

The boiler control system can adjust parameters automatically. Users can set the start-up and stop-down time, and no one needs to be on duty after the setting.
