The company is located in Linyi City (the capital of the plate). After the local environmental protection requires coal to be converted to gas, the company's thermal oil boiler and dryer have been changed to natural gas, but the cost is too high. They use nearly 80,000 yuan per day. After the transformation by our company, using their production waste sanding powder as fuel, use our biomass wood powder burner, and heat the customer's thermal oil burner and dryer at the same time. The fuel save is more than 50,000 yuan everyday, and the annual savings are about 15 million. The customer immediately renovates the company's two production lines and is currently in use.
