Ozone molecules are constantly being made. But they can be destroyed by any of a number of chemical processes, most of them natural. For example, the stratosphere receives regular injections of nitrogen-bearing compounds, such as nitrous oxide(N₂O). Produced by microbes and fossil-fuel combustion, the gas rides the rising air currents to the top of the troposphere. Forced higher still by the tremendous upward push of tropical storms, it finally enters and percolates slowly into the stratosphere.  5, record 1, English, - nitrogen%20species

Pressure Atomizing Oil Burners.... Atomizing is accomplished by pumping the oil at pressure... through a suitable burner nozzle orifice which breaks it into a fine mist and swirls it into the combustion space as a cone-shaped spray. Combustion air from a fan is forced through the burner air-handling parts surrounding the oil nozzle and is directed into the oil spray. Thus, an intimate mixture of air and oil is produced.  1, record 6, English, - oil%20spray

Oil furnaces. Indoor oil furnaces... are available in upflow, downflow, horizontal and low-boy configurations for ducted systems. They are also available as floor furnaces, wall furnaces, and free standing space heaters. Oil-fired outdoor furnaces and combination units are rare.... The ducted system, oil-fired, forced air furnaces are usually equipped with pressure-atomizing burners. The pump pressure and the orifice size of the injection nozzle regulate the firing rate of the furnace. Electric ignition is used to ignite the burners.... The combustion chamber and heat exchanger of oil-fired furnaces are normally formed as a common single chamber. It is formed from heavy gage steel into a welded assembly. The hot flue products flow through the inside of the heat exchanger into the chimney. The conditioned air flows over the outside of the heat exchanger and into the air supply plenum.  1, record 9, English, - oil%20furnace

Forced Air Wood Furnaces. Central wood-burning furnaces are controlled by a wall mounted thermostat in the living area. Temperature and fan controls are the same as those found on oil and gas furnaces. Unlike room heaters, which produce a steady heat output by periodic manual adjustments of the draft control, most wood furnaces operate in cycles. A cycle starts with the thermostat sensing that heat is needed in the room where it is located. It signals the furnace control system which opens the combustion air damper and a hot fire develops. When the air inside the furnace's sheet metal casing gets hot, a preset fan control starts the circulating blower and the warm air is moved through the ducts to all areas of the house.  1, record 10, English, - forced%20air%20wood%20furnace
