System for the dosing of additives/inhibitors containing magnesium oxide applied to fuels used for the production process of clinker/cement in rotary furnaces and steam generating boilers

Abstract

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 solid or liquid fossil and alternate fuels, preferably used in rotary furnaces for the production of Clinker / cement and in steam generating boilers. Additionally, this invention is characterized for having the power to increase the use of fossil and alternate fuels without altering the characteristics of cements or concretes as the final product of cement.

Description

FIELD OF THE INVENTION[0001]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.BACKGROUND OF THE INVENTION[0002]The world trend in the cement industry goes towards the use of alternate fuels that are increasingly polluted with sulfur, aluminum, silicon and vanadium impurities, mainly with the purpose to reduce the manufacturing costs of Clinker / cement and in the steam generating boilers with little success. The foregoing arises from the instability of operations, loss of production and damage caused to equipments by corrosion.[0003]In the last few years, the largest companies that manufacture cement and generate electri...

AI Technical Summary

Benefits of technology

The invention is a system that reduces harmful emissions to the environment by using alternative fuels, such as tires, petrochemical residues, and oil drill sludge, to produce calorific power. Additionally, it helps improve the production efficiency and reduces labor accidents caused by non-schedule stops to repair cement line production and steam generating boilers. The system includes a conveyor belt for solid fuels and a graph showing the positive effect of the additivation system. Overall, this invention helps support global ecology and the sustainability of cement production.

Problems solved by technology

The world trend in the cement industry goes towards the use of alternate fuels that are increasingly polluted with sulfur, aluminum, silicon and vanadium impurities, mainly with the purpose to reduce the manufacturing costs of Clinker / cement and in the steam generating boilers with little success.

The foregoing arises from the instability of operations, loss of production and damage caused to equipments by corrosion.

In the last few years, the largest companies that manufacture cement and generate electric power nationwide have focused on developing mechanical systems to solve a chemical problem; nevertheless, they have not been successful because they have preferred to look for other solutions rather than handling dosed additives in fossil, alternate and liquid fuels, that will solve problems arising out of harmful components in fuels.

There are additives on the market that cannot be successfully used due to their difficult handling and preservation in storage tanks; furthermore, their dosing also becomes complex, which reduces their effectiveness with time.
