Quarry Machinery Made Prior to Firing

It will be understood that the amount of water and of the solution of metallic salts to be fed to and mixed with the raw water will be determined by the amount or volume of flue gases which pass through the washer in a given time. The contents of SO2 in the flue gases may vary, depending on the coal burnt. Such contents will also be a factor in determining the amount of a given solution of metallic salts in the washing water. The proper mixing of the solution of metallic salts with the raw water and the amount of water needed for a given condition (type of coal and amount or volume of flue gases for a given time) may be automatically regulated by a controller disposed in the funnel leading to the stack or chimney, as I have indicated in Figure 1.

This controller maintains connection with the proportioning pump over the control line 3 and with the meter I over the control line 4. Both the proportioning pump and the meter i, that is to say, the supply of raw water and of the solution containing the catalyst (metallic salt solution) will therefore be controlled automatically in accordance with the demand for either or for both,quarry machinery for sale.The operation of the controller may be determined by suitable adjustment according to the coal which is being burned. This adjustment is made prior to firing a certain grade of coal. The effect of the adjustment of the controller results in a predetermined mixture of washing liquid in accordance with the coal used, and the function of the controller during the firing of this coal will regulate the washing mixture in accordance with the volume of flue gases passing through the funnel which leads to the chimney. The controller may be located either as is shown, between the washer and the smoke stack, or it may be connected so that it precedes the washer.

If the washing solution is recirculated the recirculati a eon may be controlled by the concentration of sulphuric acid, or other by-product coming from the washer....
