Boiler Efficiency | How to balance steam loads efficiently .

Aug 26, 2011· The efficiency on a lower heating value (LHV) basis increases slightly from 91.44% at 25% load to about 60% load and then tapers off. To determine burner duty, divide the boiler duty by the efficiency. Using a performance sheet obtained from a boiler supplier, one can get an idea of the fuel consumption at any load.

Purchasing Energy-Efficient Commercial Boilers .

A minimum turndown ratio of 4:1 is recommended for gas-fired, hot-water boilers. This is particularly important in condensing boilers that run more efficiently at part load. Low mass: Because boilers cycle on and off and it takes time to bring a high-mass boiler up to operating temperature, using low-mass boilers will reduce energy consumption. In addition, some boilers can be brought online …

opportunities for the hot gasses to transfer heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-

Boiler modulation – is more better? - HPAC Magazi

Boilers are rated on their thermal efficiency, which is simply the ratio of the chemical energy added to the boiler over the energy added to the boiler water. As more heat is transferred from the hot gas into the boiler water, the thermal efficiencies increase and the exiting (flue) hot gas temperatures decrease.
