对燃煤锅炉进行设计改造以及锅炉设备运行时,都需要掌握燃煤的如下性质:(1)燃烧性;(2)结渣性;(3)积灰性(亦称沾污性);(4)煤灰磨损性;(5)NO_x生成特性;(6)煤的可磨性;(7)集尘特性。本文主要介绍燃煤燃烧性、结渣性和积灰性的评价技术。一、燃煤的燃烧性
The design and modification of coal-fired boilers and the operation of boiler equipment require the following properties of coal: (1) combustibility; (2) slagging; (3) fouling (also known as fouling); 4) ash abrasion; (5) NO x generation characteristics; (6) coal grindability; This article mainly introduces the evaluation of coal combustion, slagging and fouling evaluation. First, the burning of coal
