As a particularly important part of brand building of ZOZEN Boiler, the after-sales service team always focuses on users, and considers and solves problems from the standpoint of users. Providing professional, efficient and caring service has always been the goal of ZOZEN Boiler after-sales service team.
ZOZEN WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace and threaded smoke tube to increase the heating surface, reduce the thermal stress and improve the boiler's safety performance; meanwhile, in order to reduce the heat loss caused by gas exhaust and operating costs, ZOZEN also adds energy-saving devices at the end of the flue gas duct to improve the thermal efficiency to over 98%. In addition, the two sets of boilers also meet the ASME standards, which proves that ZOZEN product quality is up to international standards.
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.
The shipment of ZOZEN SZL series chain grate boiler for R.R.P AGRO FARM.SZL series of biomass-fired boiler is one of ZOZEN’s patented products. It has the characteristics of wide fuel adaptability, less occupied area, convenient installation and high thermal efficiency. ZOZEN biomass-fired boiler is suitable for a variety of fuels such as biomass pellets, wood blocks, palm shell, rice husks, corncobs and wood waste. In order to improve the overall efficiency of the boilers, ZOZEN rationally designs different feeding systems according to the characteristics of different biomass fuels. By extending the furnace arch, increasing the height of the furnace, adjusting the width and length of grates, etc., ZOZEN has taken the lead in solving the problems commonly occurred in conventional biomass-fired boilers, such as furnace arch burning down, furnace door burnout, backfire in hopper tempering and tube shell coking.
Veolia (Harbin) Thermal Power Co., Ltd. was established in 2003 and is a Sino-foreign joint venture controlled by Veolia Group. ZOZEN customized a complete boiler system including multiple sets of WNS series gas-fired hot water boilers. This series of gas-fired boilers adopts full corrugated furnace to increases the strength and elasticity of the furnace and enhances the disturbance of the flue gas, effectively improving the heat transfer effect. The threaded fire tubes can effectively absorb the flame energy, and the heat transfer coefficient is 1.2 times higher than that of the ordinary tube. At the same time, the finned tube condenser added at the end of the flue can increase the boiler thermal efficiency to over 98%
ZOZEN YY(Q)W series horizontal thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN YLW series horizontal thermal oil heaters have wide fuel adaptability, applicable to a wide range of fuels including bituminous coal, anthracite and biomass particles; they adopt the design of square coil for sufficient heating surface, which is safe and efficient, and the thermal efficiency is leading in the boiler industry.
