ZOZEN has always been committed to providing customers with efficient and reliable heating and hot water supply equipment, and has a good reputation in the industry. The delivery of the WNS series and SZS series boilers once again demonstrates ZOZEN's commitment to fulfilling promises to customers, as well as its strict control over quality, efficiency and safety. We believe that these boilers will provide reliable protection for the production and life of our customers.
ZOZEN SZS series gas-fired hot water boiler has a capacity of 7-116MW, a working pressure of 1-1.6Mpa, and a full-membrane water-cooled wall structure. The combustion chamber has good air tightness and reduces heat loss.
As one of the professional heat transfer oil boiler manufacturers, ZOZEN Boiler has rich experience, reasonable design of heat transfer oil boiler system, and overall thermal efficiency is generally higher than that of similar products. Detailed analysis of thermal oil boiler system, which mainly consists of fuel supply system, heat transfer system of heat transfer oil carrier and heated system. The fuel can be natural gas, fuel oil, biomass, coal, etc.
Coal and biomass thermal oil heater is an important category of heat-transfer oil boiler, which is widely used because its operating cost is cheaper than that of fuel gas, and there is no need to lay fuel pipelines. The furnace body of ZOZEN coal/biomass heat conduction oil boiler adopts multi-loop coil design.
Blanking --- ZOZEN Boiler Company adopts imported CNC flame cutting machine, which can cut the steel plate with 100% automatic CNC cutting, and can cut the plate with any geometric shape by computer automatic programming, with fast cutting speed and high working efficiency, which effectively improves the utilization rate of the plate. Edge milling --- ZOZEN Boiler adopts convenient groove equipment to wash and cut the edge of steel plate according to the required angle, and the cutter head can move along with the steel plate, thus greatly improving the applicability to materials.
Welding is a vital work in the process of boiler manufacturing, and it has an important influence on the quality of the boiler. In the production base of ZOZEN Boiler, a professional boiler manufacturer, the front-line welders always ensure the quality of the boiler welding seams with their superb technology and responsible attitude. At the same time, ZOZEN Boiler has introduced the advanced welding equipment to realize the welding automation of the main components such as drums, membrane walls, serpentine tubes, steel frames, etc.
Heat treatment is an essential part of the manufacturing process, involving heating a metal or alloy to a specific temperature and then cooling it to harden the material. In the manufacturing process of boilers, the following pressure components require post-weld heat treatment: alloy steel pressure components and carbon steel pressure components which include butt joints with wall thickness greater than 30mm, the cylinders of internal combustion boilers, and T-joints with tube sheet wall thickness greater than 20mm. As a professional industrial boiler manufacturer, ZOZEN Boiler always strictly follows the boiler safety technical specifications to conduct heat treatment on specified boiler components, which effectively reduces the residual stresses in the material that have been introduced by welding and improves the boiler performance.
The boiler as a kind of common special equipment, the quality, specification and mark of its raw materials should meet the requirements of the applicable material specification. According to the different requirements of various materials purchased, ZOZEN Boiler has established a strict acceptance system to ensure the raw materials in compliance with the material specification and to prevent the unqualified raw materials entering into the production processes. For the safe operation of the boiler, sectional materials will be strictly re-inspected to ensure the boiler pressure strength.
