coke dried quenching heat recovery boiler

Many users find that coke dried quenching heat recovery boiler technology consultant at the time of introduction gas hot water boiler with heating, usually recommend more than two or two with the use of boilers; some users really do not understand this, I think manufacturers to gain profit, deliberately users select more than one boiler, it is not true, behind doing so is of great significance. 1, when the weather is not too cold, the user can choose to start one or two boilers operate at optimum operating load. 2, when the boiler requires servicing and maintenance, a table may be stopped, either high-load operation other boiler, so as not to delay the normal heating demand.

Factors affecting the thermal efficiency of gas coke dried quenching heat recovery boilers What? 1, exhaust gas temperature: the temperature of exhaust gas boiler is generally increased by 15 degrees, heat losses will be increased by 1%. 2, the oxygen content of the furnace: the excess air factor, when an excessive increase in heat losses, is too small incomplete combustion loss increases. 3, furnace pressure: positive pressure when the furnace operating conditions reasonable time, can effectively avoid the intrusion of the cold hearth, a negative pressure may increase the air ratio to increase the exhaust loss; 4, insulation factor: this factor mostly caused overhaul , when the boiler is located somewhere in the inner part faulty insulation, insulation must be removed for repair, the repair is completed after the insulation layer can not be repaired, resulting in increased heat boiler heat loss. 5, piping: soda pipe, gas pipe and smoke is no need to have some air pipe bends and valves, increasing the resistance to fluid flow in the pipeline, at the same time, some of the valve system is not fully open, to form a fluid expansion, increasing the local resistance loss of the working fluid.

The "national industrial energy-saving technologies and equipment Recommended List (2018)" key recommendation "premix wing-type vacuum condensing hot water coke dried quenching heat recovery boiler" There is a beautiful name - Thalia T6, through the rational use of the U-shaped smoke tubular, cross-wing type tube design structure, and heat transfer at the same time meet the thermal requirements, reduced to 33% of the entire area of ​​the boiler can be placed in a small area in the boiler room. At the same time the use of advanced industry premix combustion technology, will reduce nitrogen oxide emissions to 18 mg / cubic meter, well below the most stringent air pollutant emissions of Beijing, Tianjin, Zhengzhou and other cities 30 mg / cubic meter standard.
