SZS series gas-fired boilers are the main energy-saving and environment-friendly boiler products in the market at present. In order to reduce the heat loss on the surface of the furnace body, the outer package of the gas-fired boiler adopts the whole frame structure, which reduces the connecting plate between the frame and the drum, and effectively reduces the heat loss caused by heat conduction. In addition, the outer guard plates of ZOZEN SZS series gas-fired boilers can be customized as needed.
ZOZEN DZL series packaged boiler is horizontal three-pass water and fire tube chain grate boiler with a wide fuel adaptability to biomass particles, bituminous coal, meagre coal and anthracite. The boiler proper is a longitudinal single drum. The threaded smoke tubes in the drum form the convention heating surface. The drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The combustion equipment adopts the light chain grate. The boiler is reasonably arranged with primary air and secondary air, and is equipped with economizer and dust collector at the boiler end to control the NOx emission concentration below 200mg/m3. Meanwhile, the boiler realizes the stepless speed regulation of the grate via the electric control. There are also the absolute rating alarm and interlocking protection functions to make the boiler safer. It is widely used in the chemical, food, tobacco, textile, printing and dyeing, feed, medicine and building materials industries.
ZOZEN WNS series gas-fired and oil-fired boiler is equipped with the advanced condenser, which is a kind of flue gas waste heat exchanger whose working principle is the same as the economizer at the end of the coal-fired boiler. After a condenser is installed at the end of the boiler's flue gas duct, the high-temperature flue gas passes through the flue gas duct and the condenser at the same time, which can heat the water in the condenser, increase the feed water temperature and lower the exhaust gas temperature to achieve the goals of saving fuel and improving the thermal efficiency.
ZOZEN verrical gas-fired thermal oil heater is manufactured by advanced technology, which has excellent advantages in quality and performance. It has the characteristics of low pressure and high temperature, moreover, it is safe, efficient, energy-saving and environmental protection. The thermal efficiency is over 95%.
