Definitions

  • This invention is located in the field of cement production, specifically this invention refers to a system that is automated and controlled by means of a software, for the storage and application of additives and/or sulfur inhibitors containing magnesium oxide and their accurate dosing in solid or liquid fossil and alternate fuels, preferably used in Clinker/cement production furnaces and in steam generating boilers.
  • the MX 128425 document outlines the formation of a modified Portland cement, which includes the steps to subject the crude Clinker mixture of Portland cement including alumina to calcination in the absence of incorporated water steam, but in the presence of a calcium halide.
  • the purpose of this invention is to provide a system that is automated and controlled through a software for the storage and application of additives and/or sulfur inhibitors containing magnesium oxide, and their accurate dosing in liquid or solid fossil and alternate fuels, preferably used in rotating furnaces for the production of Clinker/cement and in steam generating boilers.
  • Another objective of this invention is to provide a system that will also allow to increase the stability of the operation by maintaining the calcination lines free of adherences and sticking in rotary furnaces for the production of Clinker/cement and for steam generating boilers; in the same way, it allows to eliminate the rings that are formed in the furnace pipe when solid fossil fuels are used.
  • one additional objective of this inventions is to provide a system that also carries out and stabilizes the dosing of the additive/inhibitor in variable quantities according to the Clinker production of each rotary furnace or calcination line in particular (during the production of cement) and/or the quantities of fuel consumed in the calcination line or in the steam generating boilers.
  • An additional advantage of the invention is to provide a system that considerably supports world ecology by diminishing harmful emissions to the environment, since rotary furnaces for the production of Clinker/cement may be considered to be great reactors that owing to their design, any type of alternate fuels such as tires, petrochemical residues and oil drill sludge, organic debris, solvents, plastics, etc. may be burnt/consumed to obtain calorific power
  • FIG. 1A shows a general scheme of the system according to this invention applied to solid fuels.
  • FIG. 1B shows a general scheme of the system according to this invention applied to liquid fuels.
  • FIG. 2 refers to the image of a solid fuel conveyor belt where the dosing of the additive containing magnesium oxide is carried out.
  • FIG. 3 shows a graphic where the positive effect of the additivation system is observed together with the additive containing magnesium oxide, according to this invention.
  • FIG. 4 refers to a graphic that shows the improvement in the production of a cement rotary furnace treated with the system subject matter of this invention.
  • This invention refers to a system that is automated and controlled through a software, for the storage and application of additives and/or sulfur inhibitors containing magnesium oxide and their accurate dosing in liquid or solid fossil and alternate fuels, preferably used in rotary furnaces for the production of Clinker/cement and in steam generating boilers.
  • the system allows to dose sulfur inhibiting additives containing magnesium oxide to a solid type fuel, such as petroleum coke.
  • a solid type fuel such as petroleum coke.
  • the exit of the additive/sulfur inhibitor containing magnesium oxide is directed to the petroleum coke conveyor belt to subsequently direct the material to the mill.
  • the system allows for the dosing of a liquid-type fuel of the additive/sulfur inhibitor that contains magnesium oxide.
  • FIG. 1B outlines the second mode of this invention, where the system comprises the same elements that the dosing system for solid fuels, and additionally comprises a manometer ( 10 ) and a valve ( 11 ).
  • PLC Programmable Logic Controller
  • the system/dosing subject matter of this invention is automatically activated when the solid fuel conveyor belt is turned on, which is the place where the dosing of the additive containing magnesium oxide is carried out before it enters into the coke mill ( FIGS. 1A and 2 ), the system is automatically turned off at the time the conveyor belt stops. Additionally, in the case of liquid fuels used in the steam generating boilers, the pump is permanently activated while the boiler is in operation.
  • FIG. 3 shows a graph where the positive effect of the additivation system is seen together with the sulfur inhibiting additive containing magnesium oxide, it can be seen on the upper part how the temperatures are recovered along the cement rotary furnace after the injection of the product has started, in the case of steam generating boiler, stability of the pressure thereof may be seen.
  • the furnace “cleaning” action is a conjunction/combination of this system, in the lower part it is be seen how the furnace is the furnace is completely polluted by the harmful material of untreated fossil fuels.
  • FIG. 4 shows the improvement in the production of a cement rotary furnace treated with the system subject matter of this invention, a feeding of 160 ton/h of the furnace and an 8.7% increase in the feeding of the furnace are achieved.
