Helical coil heaters refer to the thermal oil heaters with round or square helical coil structures. ZOZEN YQ(Y)W and YQ(Y)L series gas-fired/oil-fired thermal oil heaters both have the three-pass round coil structure. The conical coil is used to effectively protect the furnace wall at the boiler end. ZOZEN YLW series coal-fired/biomass-fired thermal oil heater has the square coil structure. ZOZEN thermal oil heaters are featured with high-temperature and low-pressure heating.
Energy efficient hot water boilers refer to the hot water boilers with less fuel consumption and higher thermal power than ordinary hot water boilers. For instance, ZOZEN WNS and SZS series hot water boilers are energy efficient hot water boilers for adopting the advanced burner with high combustion efficiency, energy-saving devices such as economizer, condenser, etc., and well-designed boiler structures in order to reduce the fuel consumption and improve the thermal efficiency of hot water boilers.
Oil steam boilers are steam boilers that are fired by fuel oil such as diesel oil, light diesel oil, heavy oil, crude oil, etc. ZOZEN produces two types of oil steam boilers that are WNS series oil-fired steam boiler and SZS series oil-fired steam boiler. They have the common characteristics that are sufficient output, high efficiency, low NOx emission and safe operation.
Hot water boiler thermal power refers to the quantity of heat generated by a hot water boiler per hour. Hot water boiler thermal power is usually measured with MW or kcal/h.
Coal boiler maintenance mainly refers to the regular inspection and maintenance of valve and instrument system, automatic installation system, water feeding system, fuel combustion system and ventilation system of coal boiler. In addition, coal boilers also should pay attention to the incrustation and sewage disposal problems.
ZOZEN YQL series gas-fired thermal oil heater adopts conical coil which effectively protects the furnace wall in the end region of boiler and the top burner.
Condensing boiler efficiency is the thermal efficiency of condensing boilers. ZOZEN's WNS series and SZS series condensing boilers are all equipped with condensers to lower the exhaust gas temperature and further to improve boiler's thermal efficiency (above 98%), so as to cut the operating costs of enterprise.
Boilers for the rubber industry: there are many kinds of rubber product with similar producing process, mainly including raw material preparing, plastic refining, mixing, calendering, forming, vulcanizing etc., and most of these sections needs steam. Besides, some high temperature machines such as pressing, kneading, banbury machines, vulcanization molding, injection molding machine, cement mixer, conveyor belt dryer and molds heating and insulation also need thermal fluid heater. ZOZEN's DZL series biomass-fired steam boiler, SZS series steam boiler and YQ(Y)W series thermal oil heaters are suitable for the rubber industry.
Automatic boiler control system includes regulator system and program control system to realize the automatic control of thermal process variables such as feedwater and combustion in boiler's operation. Realizing boiler's automatic control plays a significant role in boiler's stable and safe operation. ZOZEN boilers are all equipped with advanced and reasonable automatic control systems according to different fuels, structures and operation modes of boilers.
Boilers for the pharmaceutical industry: ZOZEN's WNS and SZS series gas-fired steam boiler, YQW series thermal oil heater, DZL series biomass-fired steam boiler are widely applied in the pharmaceutical industry to provide significant heat supply for pharmaceutical production lines. ZOZEN has accumulated abundant cooperation experience with pharmaceutical enterprises.
Industrial boiler systems consist of boiler proper and auxiliary equipment such as ventilating device, water feed device, dusting device and other boiler accessories. ZOZEN can customize different industrial boiler systems for different customers according to their actual demands.
Boiler inspection plays an important role in boiler's operation safety. The industrial boiler's external inspection usually is once a year and internal inspection is once every two years. In addition, a boiler should accept hydraulic test every six years. Those boilers that can not be inspected internally should accept hydraulic test every three years. Utility boiler's internal inspection and hydraulic test cycle can be adjusted according to the overhaul cycle of power plant.
