Recommended Oil Furnace/Boiler Temp? | Terry Lov

2012-2-7 · With an embedded coil you would still have to set the boiler temp at least 20F higher than what you can get away with if you had an indirect, lowering the effectiveness of the economizer. That extra 20F is a 24/365 condition. With an indirect you could safely program the economizer to low-limit a 140F before firing.

A review on biomass as a fuel for boilers - ScienceDire

Co-firing refers to the combustion of biomass and coal for power production. Co-firing of biomass and coal can be advantageous with regard to substitution of fossil fuels, reducing fuel cost and emissions of NO x and CO 2 minimizing waste and reduce soil and water pollution and increasing boiler efficiency. However, attention must be taken to

Hot Water Boiler Short Cycling — Heating Help: Th

Consider that any time a boiler's burner turns on, it takes about two minutes for it to reach peak efficiency. Warming the flue passages, stabilizing the flame, balancing emmissions (CO, CO2, NO2 etc.). If a boiler stops before that period is up (due to reaching setpoint or for any other reason) that would definitely be short-cycling in my book.
