temperature of the flue gases in a heating boiler, ZOZEN boiler assists various large building enterprises to complete boiler the low nox transformation

Under the new performance appraisal system, the original assessment criterion should be changed as well. According to the skill level and working competence of every employee, ZOZEN’s leader Mr. Zhang Guoping and department managers divided the front-line staff into five levels: senior technician, technician, senior worker, intermediate worker and primary worker. Different professional titles match different basic salaries to ensure that excellent staff with good skill, diligence and carefulness can get good salaries.

The condensate water draining performance plays an essential role in the normal operation of gas-fired boiler to prevent the emission of steam when condensate water, air and carbon dioxide are discharged. Intended to realize a better effect of water draining and steam holding, ZOZEN Boiler’s technical team improved the original boiler structure for excellent condensate water draining performance to reduce energy consumption and cut down production cost for the enterprise.

ZOZEN WNS series gas-fired boiler not only adopts the advanced low-NOx burner, but also adopts the flue gas recirculation technology to absorb about 10-30% flue gas at the boiler tail into the air inlet of the burner via the pipeline. Mixed with the combustion air, the flue gas enters the furnace to lower the temperature and oxygen concentration of the combustion zone, which finally reduces the generation of thermal NOx and makes the NOx concentration of boiler exhaust gas less than 30mg/Nm3.

ZOZEN biomass-fired boilers refer to the boilers fueled by biomass energy, which are typically energy-saving and eco-friendly products. Biomass fuel usually refers to the agricultural and forestry wastes such as various crop straws, leaves, wood chips and so on, which are renewable and recyclable. The operating cost of biomass-fired boilers is low, which is only a half of that of gas-fired boilers. However, the initial investment cost of biomass-fired boilers is higher than that of oil-fired or natural gas fired boilers. Biomass-fired boilers are good alternatives to gas-fired boilers when replacing the coal-fired boilers. At present, the technical parameters of biomass-fired boilers are 2-75 tph (rated capacity) and 2.0-116 MW (rated thermal power).

temperature of the flue gases in a heating boiler, The key processing technologies of the steel plate of ZOZEN gas fired boiler, such as the slanting of the steel plate, the circle, and the drilling of the drum, all adopt advanced CNC processing technology to reduce assembly stress and extend the service life of the boiler. Process to ensure welding quality, all longitudinal and circumferential welds are 100% radiographically inspected.

Rashid Paper Mills Ltd., established in September of 2016, is a paper manufacturer of the well-known Rashid Group in Bangladesh. It mainly produces various types of paper used for writing, printing and offset printing. It currently has two independent production lines with a daily production capacity of 200 tons of paper. It also exports high-quality paper to overseas market. In order to ensure the heat source supply of paper production lines, Rashid Paper Mills Ltd. chose to introduce the advanced ZZ series medium-temperature and medium-pressure boiler from China with a rated pressure as high as 3.82 Mpa and sufficient high-temperature steam supply, temperature of the flue gases in a heating boiler.
