Beyond Primary / Secondary Piping - Caleffi Hydronic Solutions

May 01, 2019 · Hydronic Boilers Piping Arrangements Just like we would debate over sports, music, or politics, engineers have long held strong opinions about piping arrangements for hydronic heating systems. Which is better: Primary-Secondary or Variable Primary? They each have their benefits, but most boiler manufacturers tend to side with Primary-Secondary.

Calculator: Flue Gas Analysis | Thermodyne Boilers

Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.

Flue Gas Heat Recovery Systems - TheGreenAge

Flue Gas Heat Recovery Systems (FGHRS) take advantage of heat within waste flue gases resulting from the combustion of gas in your boiler. This recovered heat is used to preheat the cold water entering the boiler, thereby lowering the amount of energy needed to warm the water up to the required level.
