tankless natural gas water heaters, ZOZEN gas-fired boiler greatly improves energy utilization
At present, ZOZEN Boiler has participated in the construction of more than 40 “Belt and Road” projects in countries and regions along the Silk Road including Thailand, Indonesia, the Philippines, Uzbekistan, Russia, Pakistan, Singapore, Vietnam, Jordan, Mauritius, South Africa, and the United Arab Emirates, and have achieved remarkable results, tankless natural gas water heaters.

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, tankless natural gas water heaters.
ZOZEN’s SZL series chain grate boiler has an independent water circulation system to ensure the safety and reliability of boiler’s water circulation. ZOZEN also designs independent water circulation systems in structure. The water circulation structure is simple and the division of water supply work is clear, which ensures that the cross-sectional area ratio of downcomer to riser is larger than 0.4 in order to ensure the safety of boiler’s water circulation under the premise that the water quality meets the GB standards.
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, tankless natural gas water heaters.

The relationship between enterprise’s sustainable development capacity and environment and society is mutually promoted and coordinated. Taking the social responsibility of protecting environment is greatly beneficial for the sustainable development of enterprise. Industrial boiler manufacturer ZOZEN has its own understanding of ecological civilization: product research and development relies on the market and it is also necessary to guide the market and provide more support for the industry in the aspects of energy saving, emission reduction, environmental protection and resource recycling. For over 30 years, ZOZEN has more than 400 kinds of boilers in four main fields that are gas-fired/oil-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters and keeps launching green products and project solutions to ensure the healthy development of the whole industrial chain.
