Regarding bio-gas combustion in boilers, I suspect that the same standards apply, whether buring bio-gas or natural gas, where the biogas would, however, essntially be a "low quality" natural gas (high CO2 and possibly moisture content, likely with significant H2S, etc).
From a code and safety, and legal, point of view, your local boiler codes will rule. For example, the Alberta Boiler Safety Association here in my geographic jurisdiction of Alberta; their safety codes act, for example, refers to other codes, including Canadian Standards Assocation for Canadian jurisdictions, etc). I would start by referring to:
- National Fire Protection Office, NFPA 85B and 85D, 8501, etc
- ASME standards (eg: B31.1 for power piping, if applicable to your posting, B32.2 for fuel gas piping, B31.8 for gas distribution systems, BPVC for boiler pressure vessels, CSD-1 for control and safety devices for automatically fired boilers, etc)
- ISA standards may also be of interest. eg: ISA–77.41–1992 — Fossil Fuel Power Plant Boiler Combustion
Controls
Manufacturers can be found, for example, in Chemical Engineers Buyers Guide (at
amongst others. Babcock and Wilcox come to mind, Foster Wheeler, etc who are boiler manufacturers, and ABB Automation, Rosemenount, Foxboro, etc, on the controls "only" side.
We are working on bio-gas fuel production processes and find this topic of interest, too. Hope this helps.
