HEAT RESISTANT WINDOWS ENABLING COKE OVEN CHARGING CAR TO BE SAFELY OPERATED BY EXHAUSTING PRESSURE OF AIR EXPANDED IN WINDOWS AND COOLING SUPERHEATED WINDOWS

摘要

PURPOSE: To provide heat resistant windows for coke oven charging car, wherein air in a window part in which pressure is increased by flame is exhausted to the outside through an air exhaust part, and the window part is cooled by automatically supplying air onto the window part by flame adjacent to the window part to prevent damage of the window part. CONSTITUTION: The heat resistant windows for coke oven charging car comprise a window part comprising inner glass(11) and outer glass(12) installed by means of a support(13) to form a space part therebetween with being spaced apart from each other in a certain distance, and a sealing material(14) surrounded on the outer circumferential surface of the support to seal the space part; an air supply part(20) comprising air supply pipes(21) connected to a lot of spots on an upper part of the support, and an air tank(22) for storing air to be supplied to the air supply pipes; and an air exhaust part(40) comprising air exhaust pipes(41) connected to lots of spots on a lower part of the support, and a cutout valve(42) installed in the air exhaust pipes so that air moving the inside the air exhaust pipes is moved in a direction.
