The National People's Congress is the first newly established formal university founded by the Communist Party of China. It is a comprehensive research-oriented national key university with a humanities and social science as the mainstay. As of September 2017, the school has 3,315 full-time teachers and 22,749 full-time students. Facing such a large group, domestic water and heating in winter are very serious and ignorable projects. Through the bidding activities, three 14MW WNS condensing gas-fired hot water boilers and two 6-ton WNS condensing gas-fired steam boilers of Zozen Boiler were successfully awarded. In this series of boilers, Zozen boilers have added a condenser at the tail of the flue, which can recycle the flue gas and increase the thermal efficiency of the boiler to more than 98%, thus saving operating costs.
In the production process, the feedstuff needs to be heated and matured to facilitate digestion and absorption by the animal. Therefore, the heating boiler is an indispensable equipment for feed production. As a national large-scale farming and animal husbandry group, the Twin Group has been dedicated to feed R&D and manufacturing, pig production and grain trading since it was founded in 1998. In the early stage, when the Yulin Twins subsidiary purchased the boiler, it was aware that the water in the heating boilers on the market was not uniformly heated, the heating was slow, the water vapor was insufficient, and the efficiency was low, affecting the feed production. After a long time visit to the major boiler plants, the principle of Yulin twin company found that, whether the welding process, production equipment, or the rational scientific design of the boiler, technology research and development team, ZOZEN boiler is the best in the country. Yulin Twins finally ordered a 12-ton SZL
Harbin Pharmaceutical Group Pharmaceutical Factory is a key antibiotic production base in China and a national large-scale pharmaceutical company. Pharmaceutical production companies cannot do without steam boilers. Nowadays, haze weather is serious and the country has strict standards for boiler emissions. When selecting the boiler, Harbin Pharmaceutical Group chose the SZW series of coal-fired steam boiler with compact structure and reasonable layout. This type of boiler has large water capacity and strong load adaptability. It is burned in a mechanized grate and burns in layers. It has good fuel combustion effect and high thermal efficiency. The product technology, performance, environmental protection indicators of ZOZEN boiler have reached the international advanced level. The person in charge of the company stated that the products of ZOZEN boiler provide practical and effective solutions for the environmental protection issues in the pharmaceutical industry.
For the winemaking, chemical, building materials, metallurgy and other industries, the boiler as a leader to ensure the normal production of enterprises, do a good job of boiler energy-saving reform is very important. Yuqi wine produce more than 30 kinds of double deck, Yuqi series of yellow wine. In recent years, on the basis of adhering to traditional brewing techniques, the company has reformed its equipment and is committed to researching and developing refreshing yellow wine that suits modern consumers' tastes. In response, ZOZEN boiler provided a 4-ton WNS condensing gas-fired boiler. The condensers at the rear of the boiler adopt finned tubes to increase the heating surface and improve the heat transfer efficiency. The fin tube is made of ND steel and can effectively solve the issue of low temperature corrosion of steel. After the restructuring, Yuqi Liquor produced about 25,000 tons of yellow wine and 3,000 tons of white wine, which greatly increased production efficiency.Harbi
