Substrate processing apparatus

A substrate processing apparatus stably and efficiently conducts a film forming process on a substrate to be processed. In the substrate processing apparatus, the substrate to be processed is supported at a position facing a heater portion, and a holding member for holding the substrate is rotated, whereby the temperature distribution of the substrate is kept uniform and a warp of the substrate is suppressed. The inner wall of the processing vessel is covered with a quartz liner which is made of opaque quartz, and thus protected from ultraviolet rays emitted from an ultraviolet light source. The temperature rise of the inner wall caused by heat from the heater portion is suppressed due to the heat insulating effect of the quartz liner. Consequently, the life cycle of the processing vessel can be prolonged.

Method of extermination utilizing heated air

A method of exterminating organisms is provided utilizing heated circulating air. First, a determination is made as to which enclosed areas of the building or other structure are to undergo extermination. This step defines an application zone. Next, a desired elevated temperature limit is established for heated air that is to be circulated through the application zone. Heaters are provided in airflow communication with the application zone, and circulation fans are positioned throughout the application zone to move the heated air for proper heat distribution. The heaters utilize an amount of recirculated air already present in the application zone to cut down on the amount of energy needed to raise the air temperature within the application zone towards the desired elevated temperature limit, and to eliminate the need for high CFM airflow heaters to achieve air temperature elevation. The temperature at various nodes within the application zone may be monitored to allow personnel to redirect circulating airflow within the application zone to balance out areas of higher air temperature with areas of lower air temperature. The method takes advantage of convection heat transfer to raise the temperature evenly within an application zone, minimizing temperature stratification which could result in ineffective pest extermination and / or damage to equipment and facilities.

Controllable air ducts for feeding of additional combustion air into the area of flue gas channels of coke oven chambers

A device for feeding and controlling secondary air from secondary air ducts into flue gas channels of horizontal coke oven chambers is shown. The flue gas channels are located underneath the coke oven chamber floor on which coal carbonization is realized. The flue gas channels serve for combustion of partly burnt coking gases from the coke oven chamber. The partly burnt gases are burnt with secondary air, thus heating the coke cake also from below to ensure even coal carbonization. Secondary air comes from the secondary air ducts connected to atmospheric air and to the flue gas channels. Controlling elements are mounted in the connecting channels between the flue gas channels and secondary air ducts which can precisely control the air flow into the flue gas channels. Thereby, it is possible to achieve a much more regular heating and heat distribution in coke oven chambers. The actual controlling devices in the connecting channels can be formed by turnable pipe sections, wall bricks, or metal flaps. It is particularly advantageous to utilize a hump-like facility (tabouret) which sits in the secondary air ducts and which is comprised of a tabouret plate with a central opening that is slid under the corresponding embranchment to regulate the gas stream. The controlling mechanism can be actuated manually, electrically, or pneumatically. Thereby, the controlling device can also be automated.
