摘要

研究了烟气参数的三维变化对管式炉辐射室内温度和辐射热流量分布的影响。通过能量、辐射传递、运动、连续性三维微分方程、k-ε 湍流模型和甲烷燃烧两步模型,对管式炉辐射室内的外部传热和传质进行了模拟。为了求解辐射传递方程,采用了离散序数法。确定了温度梯度最大的区域。

Nonuniformity of Temperature Distributions of Flue Gas Temperature over the Depth of a Tube Furnace

Nonuniformity of Temperature Distributions of Flue Gas Temperature over the Depth of a Tube Furnace

The influence of a three-dimensional change in the parameters of flue gases on the distributions of temperatures and radiant heat fluxes in the radiant chamber of a tubular furnace is investigated. The external heat and mass transfer in the radiant chamber of the furnace is modeled by three-dimensional differential equations of energy, radiation transfer, motion, continuity, k–ε turbulence model, and two-step model of methane combustion. To solve the equation of radiation transfer, the method of discrete ordinates is used. Areas with the highest temperature gradients are identified.

期刊介绍: Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
