Jan 04, 2012 · If a boiler is designed to condense, then it can tolerate return temps a lot lower. Otherwise, it's prudent to keep it at or above 130-degress for the most part (there are some exceptions). Radiators will still continue to heat when the supply temp is lower and is more efficient as long as the house remains comfortable.

In high-temperature oxy-fuel combustion processes, fuel and oxygen are mixed at the burner undiluted with recycled flue gas, except to motivate coal for coal-fired systems. This process can result in a high flame temperature (>4,500°F), which enhances heat transfer in the radiant zone of the boiler. This process also results in more viable
