Principals of Condensing Boiler System Design

Now if we can create condensing within a boiler heat exchanger, that's a lot of potential energy to be absorbed. It's also worth noting, on a factual basis, that this is not 'free' energy, this was energy that was within the gas but not transformed into heat during the combustion process.

In addition, heat is transferred from the hot flue gas (135 oF – 300 oF) to the cooling water (90 oF – 105 F) that is being pumped through the tubes. A previously developed computer simulation code was modified to predict heat transfer, condensation and pressure drop through a full scale heat exchanger. The heat exchanger was designed

Condensing Gas Boilers FAQ - Bosch Thermotechnology

A condensing boiler uses not just the heat from the combustion of natural gas, but also from this otherwise unused energy. Inside a condensing boiler, the vapor is converted back into water droplets, which surround the heat exchanger, which in turn extracts the heat and converts it into additional heating …

An Update On Oil Fired Condensing Appliances | Beckett Corp.

Water vapor, which is a by-product of the gas-fired combustion process, contains significant energy. For every pound of water vapor that is forced into a liquid state, some 1,000 BTU of latent energy, in the form of heat, are released. Effective condensing increases the efficiency by about 10% – turning more of the unit's fuel into usable heat.

Fully Condensing Stainless Steel Firetube Boilers & Water

Condensing gas combi boilers used to have two heat exchangers, as it's thought that this was more efficient. To begin with, the water was heated in the primary exchanger. As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water.

The purpose of a heat exchanger is to transfer heat from one fluid to another, hence the name. In the case of a boiler, this means transferring heat from gas to the water that will be circulating around your home to the radiators and hot water tank. Non-condensing units are fitted with just the 1 heat exchanger, whereas modern condensing units

This boiler may be arranged in the heating system as a stand-alone unit or stacked upon the heat exchanger to form a compact combination unit as shown in the diagram. In either case the boiler is a completely independent unit from the heat exchanger.

ANAEROBIC DIGESTER HEATING External Sludge Heating …

"Condensing" furnaces and boilers are so named because they utilize an added "secondary" (typically finned tube) heat exchanger to extract additional heat from the flue gases, reducing flue gas temperature from a typical 500-600°F to around 100°F, and removing the "latent heat of vaporization", which is the heat required to hold
