摘要:
A combustion system for reducing an amount of air polluting substances in a combustion exhaust gas produced in a combustion furnace comprises a combustion furnace configured to produce a combustion exhaust gas upon combustion of a combustible material, wherein the combustion exhaust gas contains an amount of air polluting substances; an analyzer suitable for analyzing the combustion exhaust gas and producing an analytical signal; a conduit suitable for conducting the combustion exhaust gas from the outlet opening to the analyzer, wherein the conduit is located adjacent the outlet opening of the combustion furnace; a controller suitable for processing the analytical signal produced by the analyzer and outputting a first control signal and a second control signal, based on the analytical signal; a neutralizer supplier suitable for supplying the combustion furnace with an amount of neutralizers to reduce the amount of air polluting substances in the combustion exhaust gas, wherein the amount of neutralizers supplied to the combustion furnace is based on the first control signal outputted by the controller; and an operating condition readjuster suitable for readjusting at least one operating condition of the combustion furnace selected from the group consisting of (1) a temperature of the combustion furnace, (2) a time for combusting the combustible material, and (3) an air flow in the combustible furnace, to reduce the amount of air polluting substances in the combustion exhaust gas, wherein the at least one operating condition is readjusted based on the second control signal outputted by the controller.
摘要:
A box member for refrigerate transportation for containing perishables therein and transporting thereby. A gas fed from a refrigerating unit flows from above to below through a gas flow path and gas flow holes of an insulating plate in the vicinity of a ceiling of the box member. A damper device for closing the gas flow path during defrosting is provided in the vicinity of an inlet of the gas flow path. An air shut-off curtain which is suspended from the ceiling and a protecting mechanism thereof are provided at the rear portion of the box member. A water tank is provided at the inside of a front corner post, and a level gauge for visually confirming the water level of the water tank and a water feed port to the water tank are provided at the outside of the front corner post. The level gauge is provided with a discharge valve and a protective net.
