Energy - Level

The combustion process of the solid fuel burner heats a water jacket installed in the firebox. Options are available for 1.5–4 kW water jackets. Water circulates through the water jacket, then back to the storage heater. Wetbacks must meet a minimum thermal efficiency of 65%.

Is a back flow preventer required on Forced Hot Water

2010-6-21 · I inspected a home with a forced hot water system today in an unincorporated part of a rural county in Colorado. The water is provided by the municipality but sewer and gas are not. In any case the boiler is connected to the main water supply just below the water heater. It seams to me that the system should include a back flow preventer.Any help is appreciated Thanks Blain

Boiler and Condenser Pressures - Rankine Cycle

Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the

Problem Oil Burner heating Back Boiler |

2011-10-15 · Basically, your new back boiler is functioning just like a radiator. You can get a one-way valve fitted into the outlet pipe of your back boiler. This is like a hinged flap which opens only one way. It will allow water to flow from the back boiler out when the fire is lighting, but will prevent water flowing into it when the oil burner is on.
