摘要： A solid fuel boiler with one or more fuel chutes configured to pre-dry wet solid fuel prior to loading into a combustion chamber of the boiler, enabling higher thermal efficiencies and burning less fuel to produce the same steam quantity. The pre-drying fuel chutes pass through the boiler where hot combustion gases radiantly and convectively—heat the chute walls to dry the wet solid fuel by radiant, convective, and/or conductive heating. Agitator mechanisms or structures within the chute mix the fuel for uniform heating, break up clumps of wet fuel, regulate the speed of falling fuel, prevent sticking, dry the fuel by means of steam and/or hot air, transport and deliver a cooling medium while a chute is offline in an operating boiler, and suppress fire using steam injection. Fuel from the chute can flow into a fuel storage bin or directly into the combustion zone of the furnace.
摘要翻译：一种固体燃料锅炉，其具有一个或多个燃料槽，其构造成在装载到锅炉的燃烧室之前预干燥湿固体燃料，从而实现更高的热效率并燃烧更少的燃料以产生相同的蒸汽量。预干燥燃料滑槽通过锅炉，其中热燃烧气体辐射和对流地加热滑槽壁，以通过辐射，对流和/或导电加热来干燥湿固体燃料。滑槽内的搅拌器机构或结构混合燃料以均匀加热，分解湿燃料块，调节燃料下落的速度，防止粘附，借助蒸汽和/或热空气干燥燃料，运输和输送冷却介质而在操作锅炉中，滑槽离线，并使用蒸汽喷射抑制火灾。来自滑槽的燃料可以流入燃料储存箱或直接进入炉的燃烧区。

摘要： A combustion air system for a recovery boiler is described in which multiple levels of secondary and tertiary combustion air ports each have an even number of ports, with the ports on opposing walls interlaced. The air system lends itself equally well to front/rear wall or sidewall applications and is especially beneficial for rectangular boilers. The air system features large and small-scale horizontal circulation zones superimposed on each other and the ability to adjust the angle of the air jets. Additional features include port dampers for the starting burners and system control based on kinetic energy.

摘要： An air port damper system for a recovery boiler employs plural louvers for altering the exit angle of air through an air port. Dampers are provided to enable adjustment of the flow through the device. Suitably, the device may be retracted away from the air port, to enable manual or automatic cleaning of the port. Further the damper system can be removed for maintenance/service purposes, without requiring shut-down of the boiler.

摘要： A cylindrical furnace having a vertical axis controls combustion. Solid fuel, particulates, and gases inside the furnace rotate around the axis, inducing radial stratification using centrifugal forces. Fuel and particulates drag on the wall of the cylinder, slipping in and out of suspension, thereby increasing particle residence times. The solid particles comprise combustible fuel particles, and non-combustible ash and contaminants. Control of the temperature of non-combustible particles and the wall surface prevents these non-combustible particles from adhering to, and building up on, the furnace wall. It is also advantageous to control the gas temperature leaving the furnace to minimize temperature-driven corrosion of downstream heat-exchange surfaces. Method and apparatuses are described to control the gas, non-combustible particle, and wall temperatures. The furnace can be integrated into a stand-alone boiler or as a combustor in which a portion of the pyrolysis gas from the combusting fuel is burned in a separate vessel.
