Abstract

The invention discloses a CFD-based simulation method for a flow field and a temperature field of a Shell gasifier, and relates to the Shell gasifier. The method comprises the following steps of 1) preprocessing: establishing a Shell gasifier physical model, determining a simulation solution domain, and dividing a computational domain grid; 2) solving a control equation by utilizing a solver: performing model setting and solving; and 3, post-processing simulation result display. The flow field and the temperature field of the Shell gasifier are subjected to simulation computing, so that certain basic physical variables in the Shell gasifier are accurately and conveniently obtained and complete in-gasifier information is provided for design and industrial production of the Shell gasifier. The physical variables in the gasifier are accurately predicted, so that the representation of a coal dust gasification process in the Shell gasifier is realized.

Description

technical field [0001] The invention relates to a Shell gasifier, in particular to a method for simulating the flow field and temperature field of the Shell gasifier based on CFD. Background technique [0002] Shell gasifier is a typical entrained-bed gasifier, which is widely used in coal-fired power generation, coal-to-methanol and coal-to-natural gas fields. Shell gasifier entrained bed coal gasification technology is an advanced coal gasification technology, which has the advantages of high gasification intensity, high carbon conversion rate, and no tar and phenolic substances in the product gas. Gazzani (Gazzani, etal. Reduced order modeling of the Shell–Prenflo entrained flow gasifier. Fuel, 2013, 104, 822-837) reported an article on the use of the reduced order model of the Shell gasifier to simulate the gasification process, and the article did not detail Information such as the flow field and temperature field in the Shell gasifier is given. However, for the desig...
