Which type of water circulation is used in industry boiler

Natural circulation boiler is a boiler which consists of two drums placed horizontally across the boiler. These drums are called water drum and steam drum. The idea of a naturally circulated boiler is, that the water will enter into the steam drum and then fall into the water drum via gravity (while being insulated from heat).
