milligrams for hydrogen, which we have successfully achieved with this design. It is worth noting that the legislative requirements in Europe demand a limit of 100 milligrams per normal cubic meter for natural gas and 137 milligrams per normal cubic meter for hydrogen, so we are significantly below these standards,” Sharon affirms.
In line with its commitment to sustainability, Dunphy now offers a full range of burners for biogas.“ While biogas itself is not unique, our ability to simultaneously fire it with other fuels to minimize carbon footprints truly sets us apart. The site may utilize biogas generated through anaerobic digestion, waste, or even human waste, making it a completely green energy source. If a site does not produce enough biogas to meet its demand, we can supplement it with natural gas or gas oil, which gives them flexibility,” Sharon explains.
Matt Brierley, Operations Director, joins the conversation to highlight Dunphy’ s Blue Jay project.“ Essentially, the Blue Jay Project was a complete energy center solution that we built within our factory, comprising of two 15 t / hr steam boilers, dual fuel ATEX rated burners
( Ethanol and natural gas) and all the peripheral components required to complete a turnkey energy center. One notable aspect of the project involved an innovative approach to steam recovery. Although the technology itself is not entirely new, a solution for high-pressure steam recovery from the various processes was adopted. Typically, many sites flash off steam at the process end and return it as a condense back to the hotwell or pressurized de-aerator at approximately 100 degrees Celsius. In this project, the condense was kept at pressure and using special pumps at the process end, the high pressure / temperature condense was pumped back to the energy center and injected directly into the boiler. This approach recovered the flash steam energy which can account for up to 15 percent. This relatively simple approach will result in significant savings, estimated to be £ 550,000 per year.
