Energy efficiency promotion type boiler

The invention provides an energy efficiency promotion type boiler. The energy efficiency promotion type boiler comprises a boiler body, a feeding pipe, a boiler bed unit and a jacket layer. The boiler bed unit comprises a boiler bed rotary table and a motor. The jacket layer is located on the outer wall of the boiler body. A longitudinal partition plate is arranged in the middle of the jacket layer, and the jacket layer is divided into a left jacket and a right jacket through the longitudinal partition plate. A water inlet pipe is arranged at the bottom of the left jacket, and a water outlet pipe is arranged on the upper portion of the right jacket. A plurality of communicating pipes are arranged inside the boiler body at intervals. The communicating pipes communicate with the inside of the left jacket and the inside of the right jacket correspondingly. The energy efficiency promotion type boiler has the beneficial effects that the heat exchange area is increased and heat transfer efficiency is made higher. 本
