Patent CA-2162769-A1 (CA)
Inventor: MORNHED GORAN
IPC: F28D20/00
Filed: 1995-11-14
Abstract: The lower-most temperature of the thermal mass in a chilled water stratified storage tank is lowered without-reducing its density by the addition of sodium nitrite and sodium nitrate, alone or in combination, preserving thermal stratification so that both warm and chilled water may be stored in the tank, a benefit not previously obtained without the use of chemicals damaging to the environment.  A solution of sodium nitrite and sodium nitrate lowers the freezing point of the cooling water to -13.2°C (8.3°F) yet still permits the chilled water to stratify in the storage tank.

Abstract: The invention relates to a method for controlling combustion air in a boiler plant, wherein combustion air is supplied into a boiler located in a boiler building. Combustion air is taken both from the inside and the outside of the building in a suitable ratio, wherein the air flow (q1) taken from outside is used to supply part of the combustion air required by the boiler. The ratio (q1/q2) is determined at least on the basis of the temperature of the outside air and the load of the boiler. The invention relates also to an apparatus for controlling combustion air in a boiler plant. The apparatus comprises a combustion air duct (C) for conveying combustion air into a boiler located in a boiler building. Combustion air duct (C) is provided with a mixing section (1) connected to both the inside of the building for supplying inside air into the boiler and the outside of the building for supplying outside air into the boiler. The mixing part (1) is further provided with control devices (2, 3) for mixing the air flow taken from the inside (q2) and the air flow taken from the outside (q1) to a total air flow (q1+2) entering the combustion air duct in a desired ratio.

Abstract: A dimming ballast for use with a phase control dimmer, and particularly a triac dimmer, includes an EMI filter selected with a high impedance to avoid excessive voltage and peak currents in the filter due to resonance with the phase controlled AC waveform at low conduction angles, when the load presented by the lamp is low.  The ballast also includes a DC-DC-converter of the switched mode type that keeps the EMI filter loaded and prevents misfiring of the triac dimmer and thereby flickering of a lamp operated with the dimming ballast.
