Description
技术领域technical field

背景技术Background technique
现有的锅炉都在炉膛内设置有水平的炉排，煤炭等燃料放在炉排上燃烧，燃烧时产生的热气上升，将锅炉中的水加热，为方便添加煤炭等燃料，作为进料口的炉门设置在炉膛的下端，进料炉门与进风口采用同一炉门，或紧邻进风炉门的上端设置进料炉门；这种炉膛结构适合煤炭、木炭等高热值燃料，随着环保节能意识的提高，采用粉碎后的植物秸秆压制而成的生物质燃料逐渐成为主要燃料之一；由于生物质燃料自身的特点是：热值低，消耗量大，燃烧过程中需不断向炉膛内添加燃料；不易烧透，堆积在一起的燃料中心部位不易燃烧，要求不断向中心吹氧，或不断翻动燃料，使其与空气充分接触；上述这两点决定了现有的燃煤锅炉的炉膛无法使用生物质燃料。Existing boilers are equipped with a horizontal fire grate in the furnace. Fuels such as coal are placed on the fire grate for combustion. The hot gas generated during combustion rises and heats the water in the boiler. For the convenience of adding fuel such as coal, it is used as a feed port. The furnace door is set at the lower end of the furnace, and the same furnace door is used for the feeding furnace door and the air inlet, or the feeding furnace door is set close to the upper end of the air inlet furnace door; this furnace structure is suitable for coal, charcoal and other high calorific value fuels. With the improvement of awareness of environmental protection and energy saving, biomass fuel pressed from crushed plant straw has gradually become one of the main fuels; due to the characteristics of biomass fuel itself: low calorific value, large consumption, it needs to be continuously supplied to the furnace during the combustion process. It is not easy to burn through, and the center of the fuel piled up is not easy to burn, so it is required to continuously blow oxygen to the center, or constantly turn the fuel to make it fully contact with the air; the above two points determine the quality of the existing coal-fired boilers.
