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.
Automation and digital equipment are widely used in boiler production in ZOZEN Boiler Modern Production Base, which can reduce manual errors and improve the quality of boiler production. Automatic welding technology in boiler drum and steel pipe is used for welding. Welding current, welding voltage, wire feeding speed and walking speed are all fixed parameters, which greatly reduces the influence of human factors on boiler quality and ensure the welding quality.
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.
In response to increasingly serious environmental problems, Ji Xiang Ju Food decides to purchase low NOx and eco-friendly gas-fired steam boiler. To meet the new requirements, ZOZEN Boiler customizes the boiler system and recommends SZS series low NOx steam boiler to ensure the sufficient heat supply for Ji Xiang Ju Food's production line. This series of gas-fired boiler adopts D-model full membrane wall structure and combustion chamber adopts narrow-spacing tube membrane wall with good air impermeability to reduce heat loss and enhance the thermal efficiency to 98% and above with the economizer at the end of flue gas duct.
SZL series vertical dual drums chain grate water tube steam and hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components. The upper assembled component is the boiler proper heat absorbing part, and the lower assembled component is of combustion equipment. The former part of the boiler proper is arranged a membrane wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace. Its rear part is arranged with dense convection tubes between upper and lower boiler cylinders. The high temperature smog after combustion shall stand for twice returning flushing transversely to the heat accepting surfaces, and shall be introduced to coal saver singly arranged, and flow into duster and exhausted from chimney in the end.
