20t steam boiler, new gerneration of ZOZEN low-nox gas-fired steam boiler is a booster of the environmental protection era
With emission requirements changing every day, it is also important to make sure that you are proactive when selecting equipment that will comply with future air regulations. Zozen Boiler has the most experience in selecting boiler equipment that will meet current and future NOx requirements.

The YQW series gas-fired organic heat carrier boiler adopts a three-pass round coil structure. The coil end adopts a necked coil which can effectively protect the furnace wall at the boiler end. It is equipped with the advanced combustion device and automatic boiler operation system. The flame formed by the fuel combustion fills the round coil and transfers the radiant heat via the coil wall, which is the first pass. The high-temperature flue gas generated by combustion gathers at the rear furnace door and turns into the second pass where is the convention tube bundles area. After the convection heat exchange, the flue gas gradually cools down and then turns into the third pass via the front furnace door where is the bundles area. Finally, the flue gas passes the economizer and is exhausted into the atmosphere via the chimney.
ZOZEN thermal oil heaters have the advantages of high-temperature and low-pressure heating, precise temperature control and good stability. More and more textile, printing and dyeing factories at home and abroad choose ZOZEN. In the textile, printing and dyeing industry, ZOZEN thermal oil heaters are mainly used for heating the drying and setting device, thermosol dyeing device, dyeing and printing device, dryer, drying apparatus, calender, flattening machine, washing machine, ironing machine, hot air stenter, etc.
The grate bracket of ZOZEN chain grate boilers adopts double-layer bracket. The upper layer uses light rail while the lower layer uses channel steel. The upper layer is heated while the lower layer is stressed. This has changed the traditional grate bracket structure which uses angle steel and friction bars and can avoid deformation. The active grate runs on the light rail. The 72-hour cold test run is carried out on the grate before the grate leaves the factory to ensure the smooth operation of the grate without deviation or jamming, 20t steam boiler.
The textile industry is a great energy consumer. As an important heat source equipment on the production line of textile enterprises, the steam boiler system can directly affect the textile quality and economic benefits of enterprises. Hebei Xindadong Textile Co., Ltd. began to implement an international industrial expansion strategy in 2013 and established a production base in Vietnam. ZOZEN Boiler customized the SZL series coal-fired steam boiler system for the company based on the local situation in Vietnam and actual demands of the production line. This kind of boiler has high efficiency, strong overload capacity and wide fuel adaptability.
20t steam boiler, ZOZEN has proved its competitive advantage with its high product quality. In the future, ZOZEN will spend more time and energy on the innovation of gas-fired boilers, and capture more market share.
