Problems solved by technology

The combustion of the burner equipped with the reheating furnace of the existing sulfur recovery device is a premixed combustion method. In the working state, the furnace wall of the combustion furnace is directly exposed to high temperature. The wall temperature rises significantly, even exceeding the limit of the refractory material, causing the lining to collapse and fail

Abstract

The invention discloses an annular wall protection combustion furnace, and a heat and mass transfer numerical simulation method thereof. The annular wall protection combustion furnace comprises a combustor and a fuel gas inlet arranged at the front end of the combustor, the shell of the combustor is provided with an air inlet, an annular wall protection air inlet, a process gas inlet annular cavity and a process gas outlet, the process gas inlet annular cavity is provided with a process gas inlet, and a fireproof heat insulation liner is arranged in the shell of the combustor. A protection gas swirl plate and shunting holes are arranged in the shell of the combustor; process gas furnace entry distribution tubes connected with the process gas inlet annular cavity are arranged in the shell of the combustor; and the process gas furnace entry distribution tubes are uniformly distributed along the circumference direction of the shell, and an angle between the process gas furnace entry distribution tubes and an axis in the shell is 45-60DEG. The combustion furnace guarantees fully pre-mixing of a combustion gas and air, and protects the fireproof material liner of the combustion furnace; and the calculating method is convenient for providing guidance in the improvement and use process.

Description

technical field [0001] The invention belongs to the design technical field of a reheat furnace for sulfur recovery in a natural gas treatment plant, and in particular relates to a ring-wall protected combustion furnace and a heat and mass transfer numerical simulation method thereof. Background technique [0002] There are three main ways of gas combustion: non-premixed combustion, premixed combustion and partially premixed combustion. The combustion of the burner equipped with the reheating furnace of the existing sulfur recovery device is a premixed combustion method. In the working state, the furnace wall of the combustion furnace is directly exposed to high temperature. The wall temperature rises significantly, even exceeding the limit of the refractory material, causing the lining to collapse and fail. Therefore, it is urgent to improve the existing combustion furnace and combustion process to ensure the safety and reliability of the lining when the combustion furnace ...
