The SZL series steam boiler stands out in the realm of industrial boilers with its distinctive design and construction. It is a water tube boiler featuring a double drum and a chain grate stoker structure that epitomizes efficiency and durability in steam generation. The SZL series comes in two main configurations: the 4-6 tph (tons per hour) range and the 6-35 tph range. The 4-6 tph models are package boilers, which means they come fully assembled from the factory, making installation and setup straightforward and less time-consuming. This design is particularly advantageous for smaller operations or those with limited space, as it negates the need for extensive on-site assembly. On the other hand, the 6-35 tph models of the SZL series are shop-assembled structures. These larger boilers come in two main parts: the upper module, which comprises the heat absorbing surfaces, and the lower module, which houses the combustion equipment.
ZOZEN boiler covers an area of 150 thousand square meters, with an annual production capacity of 2000 industrial boilers and 25000 tons of steam. ZOZEN has built six fully automatic lines for the production of convection pipe, coil pipe, threaded pipe, membrane wall, serpentine tube and header.
ZOZEN Boiler has cooperated with the Department of Thermal Engineering of Shanghai Jiaotong University to jointly develop the DZL series tri-drum biomass-fired boiler. This kind of steam boiler is a water tube boiler adopting the assembled structure with two parts. The boiler can be equipped with different grates to ensure the sufficient combustion of biomass fuels.
ZOZEN DZL series biomass/coal-fired boiler has designed with multiple separate air chambers, which can realize the air distribution at different combustion. With the speed gear, the sufficient combustion of fuel can be ensured according to different combustion rate.
ZOZEN DZL series biomass/coal-fired boiler has sufficient steam output. The boiler adopts the arched tube plates and threaded smoke tubes, which strengthen the heat transfer and solve the cracking problem of rear tube plates. Please kindly click the chat online to get more information.
ZOZEN Boiler recently provided boilers for several industries, for instance. the construction material factory, the heat supply industry, the chemical industry and the textile industry, etc.
In 2020, ZOZEN Boiler successfully supplied boilers in Venezuela, Thailand, Afghanistan, Karachi, Zimbabwe and many other countries. Especially in Afghanistan, ZOZEN provided one set of SZL series coal-fired steam boiler for Baheer Group, providing heat source for the paper production line. It successfully passed the environmental protection inspection organized by Afghan government, which had been proved to meet the local environmental protection standards due to the high combustion efficiency and super-clean flue gas emissions.
The 3 sets of 29 MW gas-fired hot water boilers serving for Jin-an Thermal Power in Tianjin were installed in 2015. The boiler is a common type for central heating which adopts the full membrane wall structure and a D-type layout. It has the characteristics of micro-positive pressure combustion, no air leakage, low heat loss caused by exhaust gas and high thermal efficiency. During the boiler manufacturing process, ZOZEN Boiler emphasizes that the welding of each baffle must be tight, and the height of welding leg should meet the requirements specified on the design drawing to ensure the leakproofness of the boiler. In addition, ZOZEN Boiler also sets strict welding standards for detailed parts including the door opening and kiln eye to prevent the high-temperature flue gas from leaking.
