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.
The packaged structure is another characteristic of ZOZEN boiler. After the gas/oil-fired thermal oil heater is delivered to the project site, it can be put into use only by connecting the gas/oil, electricity, which can save a lot of installation costs. What's more, the boiler has the patented equipment to completely remove the moisture from the thermal oil heater after the hydraulic pressure test and reduce the oil dewatering time. Take the 6 million kcal as an example, it usually takes 10 days for oil dewatering while ZOZEN only needs 2 days, which reduces the 80% time for dewatering and directly save the costs for about 30,000 RMB.
WNS series gas-fired or oil-fired hot water boiler is smoke-fire tube chamber combustion boiler and adopts two-pass or three-pass structure. It also adopts large-diameter waveform stove furnace with good thermal expansion and safety performance. There are condenser and economizer added at the end of flue gas duct which can improve the thermal efficiency to more than 95% and save boiler's operation costs.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
This series of double-drum steam boilers adopts a full membrane wall structure with good sealing performance. It is designed with large furnace to ensure full combustion of fuel and the thermal efficiency is over 98%. Meanwhile, this series of gas-fired steam boilers has reliable water circulation. Besides, the arrangement of various safety devices such as explosion-proof doors and flame detectors make the boiler operation safer and more reliable.
The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency. In addition, the water circulation structure of DHL series coal-fired boilers is identified the first domestic product in China due to its reliability and advancement. It is widely used because its comprehensive performance has exceeded similar products on the market.
Steam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. SZS gas-fired water tube boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to 30mg/Nm3.
