At each combination-therapy session, the scientists first applied radiation and then
heated the target tumor to between 40[degrees]C and 43[degrees]C.
The warm water that is run through the floor can be
heated by a gas, oil or wood boiler, a gas hot water heater, a ground source heat pump or an electric boiler.
The
heated air acts like a bubbling crucible that aids the chemical mixing of unwanted pollutants.
In the heating period, heat source water is
heated by the ground heat exchangers and by exhaust heat from the chiller.
Features: Electrically
heated platens, digital temperature control, PLC controls.
Its products include fuel-fired, electric and regenerative melting, holding, degassing, and filtration furnaces, and
heated launders for aluminum.
Leaks from condensate return lines in steam
heated multifamily buildings are a case in point.
The first looks to reduce the paths that
heated air has of escaping to the outside--i.e.
Heating of the hot air shock system is also by means of gas whereby for better utilization of the energy, the hot air is
heated again and again in a direct circuit (closed loop) and only a small quantity of fresh air required for combustion is fed in.
A technician touches the fiber with a flaming match, and the
