The working temperature of 35°C is maintained by hot water recirculating through 3 panel heaters within the tower. A propane boiler is used to meet initial heating requirements; thereafter, a natural gas boiler, modified to burn biogas, maintains the tower temperature. Surplus gas is used to heat a greenhouse and two large fish tanks.

Difference Between Biogas and Natural Gas | Compare the Difference
(inert) gas in LFG is equivalent to the inert gas entering a boiler when about six percent of the flue gas is recirculated to the boiler. Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers,
Dec 26, 2019 · A biogas heating system using boiler technology is the obvious on-site choice for anyone running a biogas plant, and these can either: – make use of a Combined Heat and Power System (CHP) Heat Exchanger utilizing the jacket heat otherwise wasted from a reciprocating gas-generator, or. – use biogas produced on-site, or delivered from a biogas plant, to create hot water for space heating by burning part or all of the biogas …
RNG is a term used to describe anaerobically-generated biogas that has been upgraded (or refined) for use in place of fossil natural gas. Raw biogas typically has a CH 4 content between 45 and 65 percent, depending on the source of the biogas, and must go through a series of steps to be converted into RNG.
Natural Gas Boiler - an overview | ScienceDirect Topics
May 01, 2011 · In order to transfer biogas into biomethane, two major steps are performed: (1) a cleaning process to remove the trace components and (2) an upgrading process to adjust the calorific value. Upgrading is generally performed in order to meet the standards for use as vehicle fuel or for injection in the natural gas grid.
