  • Publication number: 20100227283
    Abstract: A combustion method applied to a water-tube boiler and a regenerator of an absorption-type refrigerator includes a concentration ratio adjusting step of adjusting a concentration ratio of nitrogen oxides, carbon monoxide, and oxygen in a gas from a gas generation source to a predetermined reference concentration ratio, and a hazardous-substance decreasing step of decreasing nitrogen oxides, using an oxidation catalyst having characteristics of decreasing the concentrations of nitrogen oxides and carbon monoxide on a secondary side to substantially zero when the concentration ratio on a primary side is set to be a reference concentration ratio, in which the concentration ratio adjusting step detects the concentration of oxygen on the secondary side of the oxidation catalyst to control the concentration ratio so that a detected oxygen concentration becomes a set oxygen concentration substantially close to zero.

  • Patent number: 7628067
    Abstract: An insulating coating formed of engineering plastic with high-heat resistance, high-pressure resistance, and chemical resistance is formed on a surface of a water-level detecting electrode part of an electrode rod for detecting water-level attached to penetrate a metal container communicating with a boiler and including an external power supply connecting terminal part projecting outside the container and the water-level detecting electrode part projecting inside the container. One side of a power supply is connected to the external power supply connecting terminal part, and another side of the power supply is connected to the container for energization. An electrostatic capacity between the water-level detecting electrode and the container is measured by using the insulating coating on the surface of the water-level detecting electrode part as a dielectric. The water-level of water in contact with the water-level detecting electrode part in the container can be detected from the electrostatic capacity.
