Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
In these days, quality is not only one issue in manufacturing sector but to achieve a high performance, high utilization of raw material, full utilization of machines and tools, save production time, providing better work environment to the workers and safety of workers etc. The 6s workshops were held in ZOZEN and targeted to the production personnel with the aim to promote and sustain a high level of productivity and safety in our production throughout a workspace. At, present, ZOZEN has achieved initial results of 6S management.
The kick-off meeting of the Lean Factory-Standardization Project of ZOZEN was successfully held at 9 a.m. on April 20, which marked the beginning of ZOZEN's comprehensive reform. From the moment on, ZOZEN would deeply implement the concept of Operation standardization and Process standardization and comprehensively improve the internal management level and overall competitiveness. General Manager Mr. Zhang Guoping, mid and senior-level managers attended the meeting.
Jiangsu Zhongmei Cable mainly produces power cables, fire-retardant cables for coal mines, various flame-retardant and fire-resistant special wires and cables. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu Zhongmei Cable ordered two sets of 6 tph SZS condensing gas-fired boilers, which can fully improve thermal efficiency.
As a traditional industrial boiler manufacturer, ZOZEN not only pays attention to the quality of products, but also keeps up with the changing technological times. Out of the outbreak of COVID-19, a face-to-face communication with interviewees is not available. In response to the situation, ZOZEN applied video interview to recruit new employees and had good results.
ZOZEN customized the gas-fired hot water boiler system, and recommended several sets of SZS series natural gas fired hot water boilers, which had the characteristics of sufficient output, high thermal efficiency and stable operation. This series of boilers is designed with longitudinal double drums and "D" type chamber structure.
All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, soft water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. Skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
Bolivia is the highest average altitude country in the world, local Bolivian companies have higher requirements for boilers than general boilers. As the altitude increases, the atmospheric pressure and the air density decrease accordingly, which adversely affects boiler combustion.
In view of this situation, ZOZEN technical team makes adjustments from the combustion system and exhaust system of boiler, fully considering the influence of low air pressure on boiler body design and combustion. By appropriately increasing the volume of the furnace to extend the residence time of the fuel in the furnace, and the problems of slow fuel burning speed and long burning time are solved.
