evaporation per sq.metre of heating area

The coating (4) forms the fire surface (2) of the cooling element (1).

Said first heating circuit (19, 14, 18) extends over the first area (24).

The allows for a far greater surface heating area.

What this allows for is a much greater surface heating area.

The cooling element (2) has a fire surface (2) to be in contact with an interior of the metallurgical furnace.

The ceramic heater includes a heater element embedded in the surface of a ceramic substrate, and a heating surface having a JIS B 0601 surface roughness of Rmax=0.05-200 sg(m)m.

The pan (12) comprises a grate-like intermediate floor (5), which is arranged parallel to the heating surface (6, 15), wherein the heating surface (6, 15) is arranged at least along one of the lateral walls of the pan (12).

A visual indicator may provide an indication when the heating surface exceeds a predetermined temperature.

The invention relates to a method for operating a continuous flow steam generator comprising an evaporator heating surface (4), whereby a target value (Ms) for a supply water mass flow (M) is fed to a device for adjusting the supply water mass flow (M).

A hair curling device is made up of one or more heating units (40) which may be plugged into a handle (10), and into each other to make up a heating surface (50) of a selected length.

The existing heating surface has a decisive influence on the choice of your boiler.
