1 5 t oil fired package boiler, Wuxi ZOZEN boilers co., ltd. interpretate the issue comprehensively

The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. NOW, ZOZEN will help introduce the economizer. The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases the exhaust that leaves the boiler stack.

Recently, benefiting from its solid comprehensive strength, ZOZEN reached cooperation with Sinochem Exploration International Petroleum Company, and successfully settled the boiler project in Colombia. SPIC Columbia is a subsidiary of Sinochem Group's petroleum exploration and development business, dedicated to the exploration and development of long-term oil in Colombia. Boilers are essential equipment for oil exploration.

1 5 t oil fired package boiler, ZOZEN DZL series coal-fired steam boilers are horizontal three-pass water-fire-tube chain grate boilers. Threaded smoke tubes are arranged in the drum to form a convection heating surface. The drum and the water-cooled walls on both sides form a furnace radiation heating surface.

This time, GOTEC Group built a new plant in Toluca, Mexico, to expand its world map. As the important energy equipment for a new plant, the efficient and stable operation of the gas-fired hot water boilers would directly affect the company’s production efficiency and product quality. Based on previous friendly cooperation with ZOZEN, GOTEC Group appreciated ZOZEN’s WNS series gas-fired hot water boiler. Aiming at the characteristics of load changes in the actual production process of the Mexican plant, ZOZEN equipped the easy-to-operate PLC automatic control system for the boilers. The PLC automatic control system adopts advanced frequency conversion technology and fuzzy control technology to achieve high-efficiency and energy-saving operation by changing the gas volume of the boiler. After the automatic function is turned on, the controller can also automatically control the system according to the mode set by the user to ensure the safe and stable operation of the boiler.

The furnace of ZOZEN’s SZL series coal-fired boiler adopts a closely arranged water-cooled wall tube structure, which effectively prevents the erosion and radiation of high-temperature flue gas for the furnace. The furnace has large radiation area, small maintenance workload and light overall weight. In order to improve the coal applicability of industrial boilers, ZOZEN Boiler designs adiabatic furnace, water-cooled furnace, adiabatic arch, water-cooled arch, etc., and chooses different furnace structures according to calorific value, volatile content and coking characteristic index of coal provided by customers.

1 5 t oil fired package boiler, The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler.

Industrial boiler belongs to special equipment and has high requirements for product safety factors. As the domestic well-known boiler supplier, ZOZEN has advanced mechanical equipment, mature manufacturing process and guarantee of boiler quality. In addition, via the innovation and development of ZOZEN’s professional design team, the structure and material of boiler proper are continuously improved and optimized to greatly extend boiler’s service life. It is also worth mentioning that ZOZEN’s automatic boiler control system with dozen kinds of safety protection interlocks can fully ensure boiler’s safety. In the aspect of environmental protection performance, ZOZEN boilers are also outstanding. The flue gas emission of ZOZEN boilers nearly meets the EU standards. The NOx emission is low to 30mg, which realizes the goal of low-nitrogen emission.
