Isobaric air supplying and suspension active propelling unit for novel large reciprocating grate

Abstract

The invention relates to a novel large scale isobaric air supplying and suspension active propelling unit for a reciprocating grate, which utilizes aerodynamic principle and principle of mechanics and belongs to the technical field of F23L industrial air supplying of international patent classification. In order to implement an isobaric air supplying and suspension active propelling unit on a large scale industry reciprocating grate with the power of 14MW-700MW, a new task, a new subject knowledge combination and a new mathematical model concept are generated. Digital module combination is not limited by the large scale reciprocating grate boiler and the continuously developed and widened lateral width dimension thereof, and the oscillating reciprocating motion of suspension and the sealing of dynamic independent air chamber are implemented on the large scale reciprocating grate boiler in order to realize isobaric air supplying random chaining regulation and control and central control required by transverse and longitudinal combustion under the major fluctuation operation condition; difficult problems, such as bearing load, synchronous reciprocating motion and the like of the reciprocating grate consisting of multiple groups of independent units under the state of super width dimension are solved. Making the large scale reciprocating grate boiler achieve the goals of energy saving and high-efficiency combustion under set conditions becomes the core of the invention.

Description

technical field [0001] The invention relates to a device for implementing equal-pressure uniform air supply and suspension movable propelling devices in a large 14-700MW industrial reciprocating grate boiler by using aerodynamic principles and mechanical principles, and belongs to the technical field of international patent classification F23L "industrial air supply". Background technique [0002] In the prior art in this field, the grate boilers of small coal-fired reciprocating grate boilers are usually used below 14MW; they have been away from the market for many years. Because the reciprocating grate boiler is suitable for low-quality coal and plant fuels, it has attracted renewed attention when the energy is exhausted. Therefore, the grate boiler of the reciprocating grate boiler with plant fuel of foreign technology has been introduced at a huge cost, which is usually used for boilers below 46MW. Regardless of the traditional manufacturing method or the imported forei...
