热力计算的目的是为了求得沸腾层出口和悬浮室出口烟温,以及埋管受热面和水冷壁的吸热量。不论是埋管受热面、还是悬浮室中的水冷壁,它们的热力计算基本方程式有二个,即(一)烟气侧的热平衡方程式;(二)受热面的传热方程式。本文介绍沸腾层埋管热力计算方法。一、沸腾层烟气侧热平衡方程式在燃用0～8毫米的宽筛分煤粒时,其中细小的煤粒,尤其是粒径在0.5毫米以下的煤粒,会在沸腾燃烧过程中被气流带到悬浮
The purpose of thermodynamic calculation is to find the smoke temperature at the outlet of the boiling layer and the outlet of the suspension chamber, as well as the heat absorption of the heating surface of the buried pipe and the water wall. Whether it is buried heating surface, or water wall suspended chamber, their thermal calculation of two basic equations, namely: (a) heat balance equation on the flue gas side; (b) heating surface heat transfer equation. This article introduces the calculation method of boiling tube heat pipe. First, the boiling side of the flue gas side of the thermal equilibrium equation In the burning of 0 to 8 mm wide sieve coal, in which small coal particles, especially coal particles below 0.5 mm in size, will be in the boiling process by the air stream Bring it to suspension
