Flow Rate

Atomizing nozzles are available in a wide range of flow rates, all but eliminating the need for specially calibrated nozzles. Between 1.00 GPH and 2.00 GPH, for example, seven different flow rates are available. Generally, with hot water and warm air heat, the smallest firing rate that will adequately heat the house on the coldest day is the proper size to use and the most economical. Short on-cycles result in low efficiency. Another guideline is to select the flow rate that provides a reasonable stack temperature regardless of the connected load. (According to the New England Fuel Institute, aim for a stack temperature of 400°F or lower on matched packaged units or 500°F or lower on conversion burners.) If the boiler or furnace is undersized for the load, it may be necessary to fire for the load and ignore the efficiency
Spray Angle

Spray angles are available from 30° through 90° in most nozzle sizes to meet the requirements of a wide variety of burner air patterns and combustion chambers. Usually it is desirable to fit the spray angle to the air pattern of the burner. In todays flame retention burner, it is possible to fire more than one spray angle with good results. Generally, round or square combustion chambers should be fired with 70° to 90° nozzles. Long, narrow chambers usually require 30° to 60° spray angles.

Burner Air Patterns

Burner air patterns are much like nozzle spray patterns in that they fall into the same general classifications, either hollow or solid. As you would expect, a burner with a hollow air pattern generally requires a hollow cone fuel nozzle. A burner with a solid air pattern will give highest efficiency with a solid cone nozzle, but the flame will probably be longer.

Each tank needs to be installed with an oil gauge. The gauge base is treaded 2" NPT with a rubber"O-Ring" for sealing. It needs to be mounted on 1 of the plastic adapters provided with the tank with no need for pipe dope or Teflon tape on the threads. Must be hand tightened only. String and float must be released slowly during installation to prevent damage to the gearing or loosening the line off the reel. Housing design and color may differ depending on tank model.,

Bacharach N28-11 Oil Burner Combustion Test Kit Fyrite Classic Combustion Analyzers
Bacharach combustion testing kits continue to offer you the most economical means of testing for oil burner efficiency during installation or servicing. Each kit is designed with the service technician in mind and contains the instruments listed in the ordering chart.

• The fyrite carbon dioxide indicator measures the percent CO2 in a flue gas sample
• True spot smoke tester and oil burner smoke scale with the true spot smoke tester and smoke scale, you can get a accurate indication of smoke content in flue gas
• Fire efficiency finder/stack loss slide rule is a quick and easy way of determining combustion efficiency and stack loss from the results of the CO2 and stack temperature tests
• High stack temperatures are cause for special concern and may indicate a serious condition
• The intensity of draft determines the rate at which combustion gases pass through the boiler or furnace
• With the MZF draft gauge, you can determine if draft is excessive or insufficient
