Multi-mode combustion structures powered by gas, oil, electricity or mixed fuels deliver steady even heating and cut power loss. Intelligent control hardware supports remote monitoring, chemical tank parameter regulation and flux recycling to reduce waste. Thermal oxidizers handle industrial waste gas and liquid with high heat recovery, complying with global emission standards. Centrifuges remove excess zinc for uniform coating, while customized burners and hydraulic parts fit different workshop layouts. All structures pass third-party detection and meet international manufacturing norms, balancing stable coating quality, low energy consumption and eco-friendly operation for steel surface treatment factories worldwide.
