The burner structure of the blue-coke boiler is specifically designed and manufactured for the characteristics of blue coke, such as its high solid carbon content, low volatile matter, difficulty in complete combustion, and challenges in ignition. As such, it differs from the burner structure of ordinary coal-fired boilers. Therefore, ordinary coal-fired boilers cannot burn blue coke. If a coal-fired boiler is used to burn blue coke, issues such as difficulty in combustion and flame extinction may occur, resulting in extremely low combustion efficiency, reduced boiler output, high energy consumption with low efficiency, increased operating costs, and disruption to users' normal heating needs. Shaanxi Weinan Fandeli Boiler Factory has specially developed a new environmentally friendly blue-coke boiler. Additionally, they have designed a retrofit solution to convert coal-fired boilers into blue-coke boilers, equipped with specialized dust removal devices. This ensures that after conversion, the boiler is easy to ignite, easy to seal, and achieves complete combustion of blue coke. Key features include: - Internal heat exchange tubes designed as threaded smoke tubes, improving thermal efficiency by 5% and featuring self-cleaning capabilities. - Oxygen-enriched waste heat preheating for combustion support, improving thermal efficiency by 3% and extending the service life of the grate. 5. Boiler Operation: Boiler operation must be carried out by trained and certified personnel holding the "Special Equipment Operator Certificate." During use, it is mandatory to strictly adhere to operating procedures, eight systems, and six records. 6. Boiler Inspection: Boilers must undergo an annual periodic inspection. Boilers that have not passed a safety inspection are not permitted for use. Safety valves, as critical safety accessories, must be inspected annually, while pressure gauges must be calibrated every six months. Safety accessories that have not undergone periodic inspection are not allowed to be used. 7. It is strictly prohibited to install an atmospheric-pressure boiler as a pressure-bearing boiler. The use of boilers lacking any of the three major safety accessories—water level gauge, safety valve, or pressure gauge—is strictly forbidden. Fandeli Blue-Coke Environmentally Friendly, Energy-Efficient, Low-Emission Boiler: This boiler allows for interchangeable use of blue coke and natural gas by installing corresponding burners in the same unit, leading the way in safe, energy-efficient, and high-efficiency atmospheric-pressure boiler applications. Energy Efficiency: - When burning blue coke, the exhaust gas temperature is only about 60°C, saving up to 50% of blue coke compared to traditional boilers. - When burning oil or gas, the exhaust gas temperature is around 80°C, saving up to 30% of oil or gas. Environmental Protection: Equipped with balanced oxygen-enriched waste heat preheating for combustion support, vortex swirling infrared combustion technology ensures long grate life, complete combustion of blue coke, easy sealing, easy ignition, rapid fire start, and smokeless, dust-free combustion. No tall chimney is required, as exhaust gases can be directed to a designated location for treatment.
