A low calorific gas is burned without the need of mixing or burning it with a high calorific gas. The method includes introducing either combustion air or low calorific gas into the mixing chamber, introducing the remainder into the mixing chamber through the perforated nozzles such that it is injected in the radial direction at a high speed from the holes to effect the mixing of the two in the mixing chamber, and injecting the mixed gas into the combustion chamber through the nozzles of the refractory baffle. The stable combustion of a low calorific gas alone by the aid of combustion air without the need of diffusing it into the atmosphere or burning it together with an expensive high calorific gas or oxygen-enriched combustion air is thereby effected, which greatly contributes to energy saving and environmental protection.

摘要:
A melting tank for melting a gelled substance charged therein. The walls of the tank are heating. A first agitating blade agitates the bulk of the gelled substance to promote heat exchange with the walls. A second agitating blade is located closely adjacent a screen separating the gelled substance from a port at the bottom of the tank that is left open during agitation. Thereby, the melt flows down the walls of the tank and flows through the screen to the port.

An apparatus for directly monitoring microorganisms present in a liquid crises a window glass with one face in contact with the liquid. Near the other face is disposed a TV camera having an optical magnifying system for monitoring the microorganisms. A sample cell or a narrow space is formed on said one side of the window glass for direct introduction of a sample of the liquid. The sample is statically held in the cell even though the liquid is in movement. The sample is purged from the cell by feeding a cleaning fluid thereinto or by vibrating or otherside exerting physical movement on the cell, whereafter a new sample is introduced into the cell. Purging of the sample cleans the cell and is prevents it from being smudged with dregs, dirt or the like included in the liquid.

A nondestructive inspection method of inspecting a securing defect of a polymer insulator having an FRP core, an outer cover portion arranged around the FRP core, and at least one metal member secured to at least one end of the FRP core, includes the steps of; measuring an acoustic emission signal generated when the metal member is secured to the FRP core by using compression dies; and determining whether or not the securing defect is generated on the basis of the acoustic emission signal in process. Moreover, the disclosed apparatus performs the nondestructive inspection method mentioned above.
