Product Introduction
Color coating line equipped with heating, exhaust gas recovery and waste heat utilization system, effectively reduce energy consumption, emission standard is better than the national standard requirements.-Natural gas consumption is as low as 4m2/ton of steel sheet, Vocs Non-Methane Total Hydrocarbons (NMTHC) is less than 30mg.

DTO: Heating burner→High-temperature waste gas oxidation chamber→Secondary waste gas heat exchanger→Secondary fresh air heat ex-changer→Primary waste gas heat exchanger→Primary fresh air heat exchanger→Passivation fresh air heat exchanger→Pretreatment hot water heat exchanger→External exhaust fan→Chimney discharge; 
RTO: Curing oven waste gas (organized waste gas)→RTO incinerator→Fresh air heat exchanger (flue gas heat exchanger)→Pretreatment passiva-tion drying heat exchanger→Water-vapor heat exchanger→External exhaust fan→Chimney discharge up to standard(Painting booth waste gas (unorganized waste gas collection)→Collection fresh air fan→Fresh air heat exchanger→Supplementary heating furnace→Curing oven heat supply) On the premise that the thickness of the base plate is 0.3 mm and the dry film thickness of the paint is 20 um, the gas consumption per ton of steel for both DTO and RTO is less than 3 m³, and the Non-Methane Total HYDROCARBONS (NMTHC) content is lower than 15 mg/m³.
