Definitions

• furnaces which operate automatically on distillate petroleum oil to maintain a pre-set room temperature and/or supply domestic hot water.
• the furnaces and burning equipment become coated with soot and carbonaceous deposits of various kinds during operation which results in the impairment of the heating efficiency.
• the deposits may even build up to such a level, if not attended to, so as to cause a breakdown of the equipment and hence a periodic cleaning of the burner and various related parts of the furnace is recommended.
• the customary procedure followed involves the disassembly of the burner mechanism and furnace or boiler parts to expose the carboned and sooted parts to mechanical cleaning.
• the deposits are scraped, rubbed and abraded from the surfaces and the furnace and burner parts are reassembled.
• home burners generally this is done annually and this single cleaning is intended to last for the entire heating season.
• Service calls have been too frequent and hence an improved cleaning technique has been sought.
• the object of this invention is to provide a method and product for cleaning oil heating furnaces which overcomes the objections of prior cleaning techniques.
• a further object of this invention is to provide a method and product for cleaning oil burning furnaces that is faster, more economical and more efficient than prior cleaning procedures.
• a further object of this invention is to provide a chemical cleaning composition for oil heating furnaces that permits cleaning of burner parts and furnace parts without disassembly.
• a further object of this invention is to provide a cleaning solution that will dissolve deposits from burner parts and remove soot from furnace surfaces in oil heating furnaces during short cleaning periods without requiring disassembly of the burner or furnace.
• the first ingredient of our formulation comprises a highly aromatic distillate oil containing about 75100% aromatics and boiling within the range of 300700 F.
• aromatic oil of this invention such as fractions from recycle bottoms from catalytic cracking, bottoms from catalytic reforming, aromatic-rich bottoms from the production of ethylene and propylene at high temperature, Edeleanu extracts, aromatic coal tar fractions, aromatic fractions from the hydrogenation of coal or the hydrogenation of coker gas oil.
• the second compound of our formulation is also critical, being the lactate salt of 2 heptadecyl imidazoline.
• This salt appears to provide unusual cleaning ability in this environment.
• the salt appears to combine with the highly aromatic oil, butyl alcohol and metal naphthenate to provide unusual and rapid removal of carbonaceous burner deposits, soot and other furnace deposits. Without the butyl alcohol and metal naphthenate or without the specified oil the cleaning results, if any, are far less spectacular. There appears to be a synergistic action of these compounds whereby the cleaning of the furnace parts is effected to a high degree both of deposits of a firm nature as well as soot and other clinging deposits.
• the imidazoline salt structure is as follows:
• butyl alcohol a small portion of a butyl alcohol must be mixed in this formulation and that other alcohols will not operate satisfactorily. Any butyl alcohol functions satisfactorily, normal, iso, secondary or tertiary butyl alcohols being equally effective. Broadly the alcohol should be about 520% by volume of the formulation, the preferred range being about -15 by volume.
• the final material in this formulation is either a lead, manganese or copper naphthenate. These compounds work effectively with the other ingredients in the removal of carbonaceous deposits and the removal of soot from the furnace surfaces, particularly the heat exchanger surfaces.
• the liquid formulation is compounded from the ingredients disclosed above in the prescribed proportions.
• a measured quantity of the cleaning composition is fed into the burner in place of the fuel oil.
• from one to two pints of the composition can be introduced from a suitable canister directly to the suction side of the fuel pump or, if the system is equipped with a filter, directly into the filter housing.
• the formulation is passed through the burner and burns in the furnace without difficulty.
• About l-2 pints of the composition is generally adequate to clean the burner and remove the soot and deposits from the average home heating system.
• a somewhat larger charge may be used in the larger heating systems used in factories and large buildings.
• Boiler fluessoot almost completely removedth is was also indicated by a decrease in flue gas temperature from 720 F. to 600 F.
• a liquid composition for use in removing deposits from oil burning furnaces and the burners of said furnaces comprising:
• a liquid composition for use in removing deposits from oil burning furnaces and the burners of said furnaces comprising:
