Recently, ZOZEN delivered the thermal oil heaters for Hengfa Energy Saving Technology. As a leading industrial boiler manufacturer, the thermal oil heaters of ZOZEN have wide adaptability of fuels, are suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. The heaters are also equipped with the advanced burners to ensure the NOx emission is below 30mg/m3.
The skid mounted steam boiler is to place all the equipment such as the boiler proper, economizers, burners, valve instruments, electric control cabinet, water treatment, economizer circulating pumps, feeding pumps, deaerators on one or two skids to form an integral movable boiler system. All the pipes and valves on the skid have been installed, furthermore, the connecting pipes between the skids have also been installed in the factory, which can save plenty of costs for clients. This kind of boiler is especially suitable for the food industry, the chemical industry, the textile industry, the medicine industry, the rubber industry, the building materials industry and so on.
A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
ZOZEN will held regular exchange training sessions. On the one hand, it helps employees to better understand the company's business, speed up the company's development process, and resolve any skills gaps. On the other hand, training can stimulate employees' confidence and improve their subjective initiative. Employees gained a lot from this gas-fired boiler knowledge training, laying a good foundation for upgrading higher quality products.
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 WNS series gas-fired (oil-fired) boilers adopt large diameter corrugated furnace for sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
The company is an auto parts company mainly engaged in the production of automotive plastic inner and outer trim parts, epp foam parts and engine plastic parts. ZOZEN provided WNS series gas-fired steam boiler for the company. This series of condensing gas-fired boilers is horizontally arranged, compact in structure and small in floor space. The combustion chamber adopts a large-diameter corrugated furnace to reduce the thermal stress and enhance the smoke disturbance, therefore, improving the h...
In the process of milk powder production, a large amount of steam is required in various process steps such as sterilization, concentration and drying. ZOZEN provided several sets of SZS series gas-fired steam boilers for this milk powder company. This series of gas-fired boilers adopts water-cooled full-membrane wall structure and conducts air-tightness test before heat preservation to ensure that the boiler has no cross-smoke phenomenon during micro-positive pressure combustion, which also hel...
