The HERU in pyrolysis mode produces gas, whilst the gas is being produced at a low-temperature pyrolysis (achieved by the patented heat pipe technology) it also releases chlorine which condenses on the heat exchangers. This chlorine is then sent to the sewer with the water. We know chlorine in water is commonplace, however, we don’t want the chlorine to remain in the char which we will later combust. If left in the char it creates dioxins. With no chlorine present dioxins are not formed during the combustion phase. A huge breakthrough!
This gas is sent to the boiler down a metal pipe (just like it does with your normal gas or oil) and is then combusted by the boiler. While the HERU is releasing the gas to your boiler, your boiler will slow down the gas it takes from the mains supply.
In simple terms, the exhaust of the HERU is your boiler exhaust.
The HERU in combustion mode produces exhaust just like your BBQ and this exhaust is cleaned using our patented water screen filter. The exhaust is scrubbed with high-pressure water mixed with a small amount of detergent. The detergent contains potassium. This solution scrubs the exhaust removing the nitrogen oxides and puts them in the water/ potassium/detergent solution which creates nitrates. The nitrate solution is processed by the sewerage company. Nitrates are good when applied correctly to the land at the correct time of the year as fertiliser.
The exhaust is then sent to your boiler and the boiler combusts the non-combusted carbon (essentially recovering energy) and at the same time acts like the catalytic convertor on your car exhaust, cleaning the exhaust to continue meeting boiler regulations.
