1.1 Pre-Certification

Biomass Steam Boilers CE certication process is quite complicated, below are a few
key points. Thus everyone may have a preliminary understanding of the certification
process.
The company shall firstly select a suitable authorized body (Noti ed Body) and entrust
them to carry on the certification over biomass steam boilers. Specific certification mode is determined by the two parties through consultation.

1.2 Data to be Submitted for Certification

After signing the contract, NB will request the manufacturer to submit data for
conformation, including basic data of manufacturer, basic data of the biomass steam
boilers, list of major parts, main mechanical and electrical drawings, related calculation book, welder and NDE personnel quali cation, major pressure part material certificate, risk assessment analysis report, description of safety protection device in mechanical system, product self-declaration (conformity statement), etc. After conformation of these data, NB will perform relevant on-site inspection, including personnel, equipment, steam boiler performance test, etc. They will issue relevant certi cates after conforming compliance with the requirement of each directive.

1.3 Design Standard for Certified biomass steam boilers

As mentioned earlier, PED is not a mandatory technical standard, it only stipulates basic safety requirements for the biomass boiler. The manufacturer can select a design and manufacture standard according to the actual situation. For export steam boiler, domestic manufacturers generally choose ASME code for design and manufacture, since it is relatively close to the requirements of foreign countries. Some users need biomass steam boiler with ASME stamp, so manufacturer will choose ASME code as the basis for design.
