    • Printing plate production apparatus wherein a latent image is formed at the surface of photoconductive insulating sheet, either by an optical system for effecting sheet exposure or by a laser emission scanning system which constitutes the terminal of a facsimile transmission system, this latent image is developed by toner particles, for example, which are applied on, but not fixed on the photoconductive sheet, the developed image is temporarily transferred onto a printing plate with which the photoconductive sheet is brought into pressure contact, and the printing plate carrying the developed image is exposed to light which may effect chemical changes in the printing plate to harden portion thereof unprotected by toner particles after which the printing plate receives treatment to remove toner particles and unhardened portions thereof. In the means of the invention a sheet carrying a developed image initially transmitted by a single facsimile transmission system may be employed as a master copy which is mounted in the exposure system and serves in production of a plurality of identical printing plates.

    • Exhaust gas from combustion equipment such as a boiler is brought into contact with an absorbing liquid to absorb sulfur oxide from the exhaust gas into the absorbing liquid. Limestone particles having larger diameters are selectively retained in a zone wherein the absorbing liquid that has absorbed the sulfur oxide from the exhaust gas is neutralized. The absorbing liquid containing water and the gypsum thereby formed, as main constituents, are selectively drained from the neutralizing zone and recycled for renewed contact with the exhaust gas. Because of the possibility of a large decrease of desulfurizing performance due to a variation in the load on the boiler, etc., at least one of the following is monitored: pressure drop across the neutralizing zone, torque of a stirring device, solids concentration in the absorbing liquid, specific gravity of the absorbing liquid and viscosity of the absorbing liquid. Responsive to the monitored parameters outlet SO.sub.2 concentration is controlled within a predetermined range by regulation of at least one of the following: flow rate of the absorbing liquid circulated into contact with the exhaust gas, amount of the solid desulfurizing agent added to the absorbing liquid, particle diameter of the solid desulfurizing agent and speed of agitation of the solid desulfurizing agent in the neutralizing zone.

    • Optimum overall operation of a whole plant including a combustion unit such as a boiler and a wet-process flue gas desulfurization unit comprising an absorption column for removing sulfur dioxide from a flue gas from the combustion unit by absorption using a slurry of an absorbing agent such as limestone powder circulated through absorption column, recycle pumps for circulating the slurry through the absorption column and oxidation air blowers for supplying an oxidation air to the absorption column and a recycle tank is controlled by anticipating a future pH value of the circulating slurry and a future inlet sulfur dioxide content of the flue gas from a present pH value of the circulating slurry and a present inlet sulfur dioxide content of the flue gas and their change rates by computing, anticipating a future desulfurization ratio from both the anticipated pH value and inlet SO.sub.2 content and a recycle rate of the slurry, and controlling the recycle rate of the circulating slurry on the basis of the anticipated desulfurization ratio, where a desired desulfurization ratio can be readily and continuously maintained against any change in fuel species and load of a boiler with reduced utility consumption.
