Abstract: PROBLEM TO BE SOLVED: To detect an abnormality occurring in the ventilation/discharge path of a burner accurately by detecting an abnormality in the ventilation path based on a state quantity associated with the load of a DC motor and a predetermined threshold value. SOLUTION: A switch comprising means for detecting temperature in the vicinity of a combustion chamber, i.e., an overheat prevention thermistor 51, is turned on/off by comparing a voltage detected by the overheat prevention thermistor 51 with a reference voltage. When the temperature detected by the overheat prevention thermistor 51 exceeds a specified level, an overheat prevention thermo 31 opens the circuit to interrupt power supply to a relay coil 58 thus releasing a normal open terminal 59 and stopping combustion. Further, the overheat prevention thermistor 51 is connected with a control circuit receiving the temperature detected by the overheat prevention thermistor 51 in the form of a signal. Every time when the signal is detected by an RAM in the control circuit, the data is rewritten and stored.

Title: Production of water absorbing brick using fly ash and its caked body
Inventor: KOYAMA HISAJI
IPC: C04B35/00
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To produce a liq. absorbing brick by mixing powdery fly ash with a specified amt. of gypsum, adding water, mixing them and carrying out sintering by heating. SOLUTION: The fly ash is powdery fly ash generated in large quantities from a dust collector for removing fly ash contained in waste gas from a thermoelectric power plant with a boiler which burns ash-contg. coal. The fly ash is mixed with <=50 wt.% gypsum and the objective liq. absorbing brick is produced or the fly ash is mixed with <=10 wt.% gypsum and a colored brick having low liq. absorbing property is produced. Sintering by heating is carried out by heating at 1,200 deg.C for about 2 hr in an electric furnace, etc. Water of crystallization in gypsum finely dispersed in fly ash in a molded body decomposes and evaporates in sintering, generates fine voids in the resultant caked body and imparts water absorbing property and water permeability.  The amt. of water absorbed in the caked body and the strength of the caked body can be controlled by regulating the mixing ratio of gypsum.
