摘要： PURPOSE:To peel off and disperse adhering ash from heat transfer pipes by permitting a heating means to perform heating from room temperature over specific temperature and allowing the device to be rapidly heated so as to form enough temperature difference to form an internal stress discontinuous part between the layers of a boiler heat transfer pipe surface part and the adhering ash. CONSTITUTION:The heat expansion characteristic of adhering ash rapidly changes in the range of 200-300 deg.C, particularly 250-300 deg.C by the change of a crystal structure. A heating means is allowed to heat to form temperature difference so as to form an internal stress discontinuous part in the boundary surface of a boiler heat transfer pipe surface part and the adhering ash or in the layer direction of the adhering ash fixed on heat transfer pipes and the adhering ash is embrittled or peeled off from the boundary surface between the heat transfer pipes and the adhering ash. For instance, after the adhering ash 22 fixed on and under of the heat transfer pipes 20a to be cleaned is irradiated by high energy visible rays and near infrared rays to peel off, disperse and remove, the heat transfer pipes 20a are put between both the sides with the use of a heater body 1 to whole-circumferentially irradiate the adhering ash 22 so as to peel off and disperse.

摘要： PURPOSE:To prevent dust and dirt from adhering to optical fiber and enable accurate identifying of flames by forming a protruding curved head to which the end face of optical fiber is exposed and facilitating the flow of cooled air in a flame monitor for combustion equipment. CONSTITUTION:The end face 23a of a support member 23 which forms the front surface of an illumination head 20, is formed in curved shape. Optical fibers 24a, 24b, and 24c are respectively protruded through penetrating into a support groove. An optical head 20 formed in this manner, is arranged at such a position which allows a peep to the outside of a protection member 14 from a slit 16 for the protective member 14. When a cooled air 21 is passed to a flame monitor, the cooled air 21 flows along a side 23c of a support member 23. However, the cooled air flow is separated at a location slightly on the down stream side of a curvature generation section 23d of a side 23c. As a result, a thin dead water region H may be generated along the end face 23a. To eliminate any possible troubles caused by the generation of the aforesaid dead water region, the respective end faces of the optical fibers are adapted to protrude from the dead water region H. Therefore, this construction makes it possible to wipe off dust and dirt, even when adhered to the end faces, thereby enabling constant monitoring of the flames.

摘要： PURPOSE:To increase the output of an acoustic element by employing a printed wiring made of a thin good conductor for the electric good conductor connecting electrodes at an interval arranged alternately with a piezoelectric element so as to prevent the reduction in the acoustic sensitivity and noise generation. CONSTITUTION:Plural electrodes 2 are arranged alternately cylindrically with the piezoelectric elements 6 and they are connected by two printed wires 4 at an interval. In this case, the cross point with the electrode 2 not connected is insulated by an insulation layer 5. The entire element is covered by a coating member such as a rubber of a vinyl resin for water tightness and electric insulation, but because of the employment of a thin printed wiring, the reduction in the acoustic sensitivity due to the production of an air layer or noise increase caused frequently in a conventional element is prevented. Since no soldering is required to connect the electrodes 2 and the printed wiring 4, it is possible to make the width of the electrodes narrow, the number of split outputs in the circumferential direction is increased to increase the acoustic output and to reduce noise.
