The boiler is one of the important equipment in its automated production line. The sterilization and disinfection processes during the processing require the steam provided by the boiler.
Steam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. Ltd is one of large paper mill in Thailand, producing pulp, mechanical pulp, paper, board. Steam is an essential element in their production process. With the expansion of business and scale, the paper mill's demand for steam is increased by years. Therefore, Thai Development Industrial Paper Co. Ltd needs to order several sets of new steam boilers. Coal is used to be the boiler fuel in this paper mill so that they pay great attention to the combustion efficiency. After knowing their actual situation, ZOZEN’s sales manager has supplied 15tph SZL series water tube steam boilers for the company. This series of steam boiler is adaptable for all kinds of coal. Unique chain grate produced by ZOZEN is adopted for the fuel to be fully burned. Meanwhile, rational air register is designed to improve combustion efficiency.
Thermal oil heater is used to provide heat energy for the reaction and fractionation process of residual oil hydrogenation in chemical industry. Shandong Guangyue Chemical Co., Ltd. is a new comprehensive chemical enterprise, which is engaged in petroleum processing, warehousing logistics and international trade services. The construction of its second project starts in 2018, planning to build 1.6 million tons residual oil hydrogenation each year. ZOZEN has rich experience in chemical industry. ZOZEN’s manufacturing technology of thermal oil heater is unique and inimitable, ensuring the high quality of boilers. After professional explanation by ZOZEN’s engineer, this project leader ordered one set of 21 MW YQL series gas-fired thermal oil heater. This thermal oil heater adopts multi-return coil tube design, which features safer operation, sufficient heating surface and 95% thermal efficiency. It is also equipped with low nitrogen burner for energy saving and environmental prote
