Scope

NB/T 42031-2014 is the English-translated version of 生物质能锅炉炉前螺旋给料装置技术条件.

NB/T 42031-2014 is a recommended energy industry standard of China for the screw feeding device placed in front of the furnace of a biomass fired boiler.

It states the technical requirements and the main performance indicators of that device through its whole course in the works and on site: design, manufacture, assembly, testing, installation and commissioning, and then painting, packaging and inspection.

The device is the one that carries the fuel forward into the furnace, so the standard belongs with biomass boiler equipment rather than with the boiler pressure parts.

It is classified J98 and ICS 27.060.30, and it quotes GB 5226.1, GB/T 15706-2012, JB/T 1615 and NB/T 47038 among others. Issued on 18 March 2014, it has applied since 1 August 2014.
