Carbotrial Ltda. has developed to level I pilot an oven of intermittent operation for coquing coal of different contents of volatile material improving the quality of the coke, yield of the raw(unripe) coal, times of coquización, size of the oven and facility of the process. An efficient mechanism of evacuation and elimination of volatile links the being to the process of coking coal of volatile high places today in day used largely like thermal coal.

In the metallurgical sector and for experience of its technical direction the same oven serves industrially for hematite process for magnetite across processes of calcination turning them useful and suitable as metallurgical load in the processes of production of steel in high ovens.

In devolping the idea of producing SPONGE IRON by small parts, stationaly , making a mixture (mixing) adapted with coal. - The difference takes root in while the coal to coquizate uses fuel and when it treats itself in hematite process it is necessary to use a fuel that can be propane gas or natural gas.

Carbotrial Ltda. had designed and constructed a coal feeder used in brick industry with the following characteristics:

Feeder of intermittent pneumatic coal, for any type of oven or for any system of nourishment of materials of thin grain that can be used to do mixtures (mixings) that imply regulation of flow or using the gravity.

Fundamentally it handles two parameters quantity of material for operation and frequency of the operation.

In brick industry and especially in the operation of the ovens of calcination there exists a cargo that is that of "Fireman" who is the person who takes charge feeding the coal who extracts very good samples with a minimal consumption of coal but this does not mean that it is the ideal consumption of coal.

Our coal feeder modifies the fireman due which responsibility will be maintain the tolves at the indicated level, allowing the coal feeding in a perfect programmed way, with a high level of sensibility which also allows to establish optimum levels of coal consume and burning efectivity with taking decitions in a superior level in according to statistics obtained mean while.

It can be perfectly establish according to the operation rithm by will in function of sales or the dry brick disponibility, how much coal it wil be consumed by hour, by day, by month, etc
