Abstract
An anhydrous ammonia injection apparatus is disclosed for injecting anhydrous ammonia into the soil. The apparatus includes a tank adapted to contain liquid anhydrous ammonia and a conduit extending between the tank and a pump. The pump is configured to variably increase the pressure of the anhydrous ammonia within the conduit. The apparatus also includes a restrictive orifice in fluid-flow communication with the conduit downstream from the pump. In addition, the apparatus includes a terminal outlet connected in fluid-flow communication with the conduit for discharging the anhydrous ammonia from the apparatus. The restrictive orifice cooperates with the pump to maintain a pressure within the conduit therebetween that is greater than the vapor pressure of the anhydrous ammonia.
