Installation has recently started for multiple dual-fuel hot air furnaces used in feed production lines. The systems are designed to use local biomass and coal as fuel. Compared with oil and natural gas, these fuels are lower in cost and easier to source locally.

The hot air furnaces feature stable combustion, high hot air cleanliness, compliant emissions, simple operation, and low operating cost. The technology has applied for more than ten national invention and utility model patents.

The systems are widely used in industries such as daily chemicals, fertilizer, building materials, and feed production. More than 800 sets have been used by customers worldwide and have achieved strong economic benefits.
