Example Embodiment

[0024] The technical solution of the present patent will be described in further detail below with reference to the specific implementation. The parts of the technical features or action principles described in the present invention that are not described in detail are the prior art adopted.

[0025] The present invention is based on the numerical simulation of the coal seam-fired industrial boiler energy-saving evaluation mode, including the following steps:

[0026] 1) Establish the numerical calculation model of combustion in the coal seam: use the one-dimensional unsteady model as the numerical calculation model, use PHOENICS to establish the numerical calculation model of the combustion in the coal seam, and use the one-dimensional instability when the initial conditions and external boundary conditions are the same. The static fixed window model approximately describes the combustion process of the coal seam on the continuous grate, and the primary air and upper radiation...

Abstract

The invention discloses an energy-saving evaluation mode for a coal-fired grate-fired industrial boiler based on numerical simulation, and the mode comprises the following steps: 1), building a combustion numerical calculation model in a coal-fired grate; 2) setting a coal-fired layer calculation grid; 3) carrying out bed primary air distribution; 4) meshing the hearth model; (5) carrying out FLUENT calculation; 6) analyzing simulation results. The invention belongs to the technical field of boiler energy-saving evaluation, and particularly provides a coal-fired grate firing industrial boilerenergy-saving evaluation mode based on numerical simulation, which is used for carrying out numerical simulation on a boiler combustion process, is convenient for finding problems existing in boiler heat supply, improves the boiler energy-saving efficiency and accurately evaluates the boiler energy-saving property.

Description

technical field [0001] The invention belongs to the technical field of boiler energy-saving evaluation, and specifically refers to an energy-saving evaluation mode of coal-fired bed-fired industrial boilers based on numerical simulation. Background technique [0002] Industrial boilers are major energy consumers in my country, consuming about 400 million tons of coal each year, accounting for one-third of the country's raw coal production. At present, my country's industrial boilers are mainly layer fired, and chain grate boilers are the main ones. The design efficiency is generally between 72% and 80%. To 50%, the waste of energy is quite serious, and about 60 million tons of coal is used for nothing every year. Energy is an important material basis of the national economy and a basic condition for human survival. The electric power industry is an important part of the energy industry. China is a big country of coal production and consumption. At present, coal provides 75%...
