On the tire production line, processes such as calendering, vulcanization, and drying all require stable thermal energy support provided by the boiler. Jiangsu General Technology Co., Ltd. is a modern high-tech enterprise focusing on the R&D, production and sales of various tires. It belongs to the Hongdou Group and is one of the leading enterprises in the replacement market for all-steel truck tires in China.

Under the global economic integration environment, Jiangsu General Technology Co., Ltd. established a new production base in Thailand in January 2019. As an important energy equipment of the production line, whether the boiler can operate efficiently and stably will directly affect the production efficiency of the enterprise and the performance of tire products. After multiple comparisons and screenings, General Motors chose to cooperate with Zhongzheng Boiler, which has key core technology, excellent product quality and perfect service. According to the actual working conditions of the production base in Thailand, Zhongzheng Boiler recommended the SZL series biomass steam boiler for it. This new type of biomass boiler has the advantages of compact structure, safety and efficiency, and sufficient output. It is the leading product in the boiler industry. According to the characteristics of the fuel, the technicians of Zhongzheng have rationally designed and optimized the feed hopper, the width and length of the grate; the large furnace volume reduces the heat load and reduces the occurrence of coking in the furnace. At the same time, the boiler grate adopts a light chain grate, and the lower part of the grate is equipped with a segmented air bin and an air regulating device to meet the air volume required by the fuel in different combustion stages, to achieve precise air distribution, to ensure the full combustion of the fuel, and the thermal efficiency to reach 88 % Above, all indicators have reached the international advanced level.
