Precipitated silica is widely used in rubber, tire, and coating industries. As a white powder material, it requires extremely clean heat sources during production.In the drying process, high-temperature clean hot air at 400–500C is typically required. Conventional direct-fired hot air furnaces can meet the tempera...

In the calcium carbonate industry, especially in the powder drying process, there is a high requirement for heat sources. Typically, clean hot air at around 350C is needed for drying.

In the past two years, a very clear trend has emerged: more and more factories are quietly switching their energy sources.Not because of environmental inspections — but because the costs have become unbearable.

For natural gas-fired steam boilers, key challenges include significant natural gas price fluctuations, high fuel costs (up to RMB 280 per ton of steam), and strong dependence on fossil energy.By leveraging the advantages of wood chip fuel—stable pricing, abundant supply (from agricultural and forestry residues), a...

A steel plant in Shandong previously relied on natural gas as the main fuel for its billet heating process, and has long faced key challenges such as high fuel costs, significant fossil energy consumption, and increasing environmental pressure. The specific situation is as follows:
