3 macrotaxonomy imported burner fire tube steam boiler 4 ton per hour steam boiler fuel can be divided in accordance with the electric steam boiler, steam boiler fuel, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small single, double return the vertical structure, large steam boilers and more horizontal structure of three return. Vertical fuel gas steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. Horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving and economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.

Our jewelry processing company in the automotive production, many processes require energy, to be honest we really a headache on the choice of the boiler, thanks met specializes in the research and production of fast square boiler boiler! The purchase of two Taipower hot water boiler, tangible help us save a lot of costs. --customer feedback

6 tph WNS series condensing gas-fired imported burner fire tube steam boiler 4 ton per hour for food industryFounded in 1991, Sichuan Liji Pickles & Flavouring Co., Ltd. is a large-scale agricultural and sideline products processing enterprise mainly engaged in the production of pickles, seasonings and red oil series dishes. In order to greatly improve production efficiency and effectively guarantee the stability of product quality, Liji Pickles & Flavouring introduced a series of automated production lines. The boiler is one of the important equipment in its automated production line. The sterilization and disinfection processes during the processing require the steam provided by the boiler.After inspecting many boiler manufacturers, ZOZEN's high-quality equipment and refined services won the trust of Liji Pickles & Flavouring and the company decided to purchase one set of 6 tph WNS series gas-fired steam boiler. This series of gas-fired boilers adopts a full corrugated furnace to enhance the smoke disturbance and effectively improve the heat transfer effect. The threaded tube is a high-efficiency heat transfer element developed by ZOZEN for many years, which can effectively absorb the flame energy after continuous optimization. With the finned tube condenser added at the tail of the flue, the boiler thermal efficiency can be as high as 98% as well as reducing the exhaust gas temperature. In addition, The fully automatic intelligent control and safety detection device ensures the safe operation of the boiler and provides a stable and reliable heat source guarantee for the efficient operation of the Liji Pickles & Flavouring automatic production line.

Boiler efficiency calculation formula

Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently. The thermal efficiency of our coal-fired boilers is 84~92%, the efficiency of fuel and gas boilers is 96~99%, and the efficiency of biomass boilers is 86-93%. The higher the efficiency of the boiler, the better the heat transfer performance. Increasing boiler thermal efficiency can reduce boiler fuel consumption and reduce boiler operating costs. Increasing the thermal efficiency of the boiler is to increase the effective use of heat and reduce the heat loss of the boiler. The key point is to reduce the heat loss of the boiler exhaust gas and the loss of mechanical incomplete combustion.
