DL/T 831-2015 (English Version) PDF

Scope: This standard stipulates the main criteria and relevant limits for selecting the combustion mode and furnace characteristic parameters of large-capacity solid-state slagging pulverized coal boilers based on the designed coal quality. It also puts forward requirements for the design of the furnace and burners. This standard is applicable to large-capacity boilers with a maximum continuous evaporation capacity of 1000t/h ~ 3000t/h.
