Disadvantages such as high gas blackness.
实用新型内容 Utility model content
实用新型要解决的技术问题是：提供一种立式煤气化节能锅炉，该锅炉燃料燃烧彻底，热效率高，节能效果好。The technical problem to be solved by the utility model is: to provide a vertical coal gasification energy-saving boiler, the boiler burns fuel thoroughly, has high thermal efficiency and good energy-saving effect.
解决技术问题所采取的技术方案：一种立式煤气化节能锅炉，包括锅炉本体，在锅炉本体内设有水管对流管束和炉膛，炉膛内设有有孔炉拱，炉拱将炉膛自上而下分为燃烬室和煤气发生室，在煤气发生室的炉壁上开有填煤门和清渣门，煤气发生室的底部设有炉排，炉排下为储渣室，储渣室接一次送风管道，在煤气发生室的炉壁上开有连接二次送风管道的二次风进口。The technical solution adopted to solve technical problems: a vertical coal gasification energy-saving boiler, including a boiler body, a water pipe convection tube bundle and a furnace are arranged in the boiler body, and a perforated furnace arch is arranged in the furnace, and the furnace arch connects the furnace from top to bottom. The bottom is divided into an ember chamber and a gas generation chamber. There are coal filling doors and slag removal doors on the furnace wall of the gas generation chamber. There is a fire grate at the bottom of the gas generation chamber. Below the fire grate is a slag storage room. The primary air supply pipe is connected, and a secondary air inlet connected with the secondary air supply pipe is opened on the furnace wall of the gas generating chamber.
作为本实用新型的改进：在燃烬室的炉壁上开有连接三次送风管道的三次风进口。As an improvement of the utility model: a tertiary air inlet connected to a tertiary air supply duct is opened on the furnace wall of the ember chamber.
作为本实用新型的进一步改进：二次风进口、三次风进口沿炉膛内壁切向设置。As a further improvement of the utility model: the secondary air inlet and the tertiary air inlet are arranged tangentially along the inner wall of the furnace.
作为本实用新型的另一种改进：在水管对流管束两侧与炉膛内壁的间隙处，设有封堵炉墙。As another improvement of the utility model: a sealing furnace wall is provided at the gap between the two sides of the convection tube bundle of the water pipes and the inner wall of the furnace.
有益效果：本实用新型的立式煤气化节能锅炉，由于在炉膛内设有有孔炉拱，限制烟气的快速排出，增加烟气在炉膛的停留时间，提高了炉膛的温度，同时，炉膛温度的提高也有利于燃料的充分燃烧，使得本实用新型的立式煤气化节能锅炉燃料燃烧彻底，热效率高，节能效果好；由于采用了储渣室接一次送风管道，在煤气发生室的炉壁上开有连接二次送风管道的二次风进口的技术特征，为燃料的燃烧提供了充分的氧气，使燃料的燃烧更彻底；由于采用了在燃烬室的炉壁上开有连接三次送风管道的三次风进口的技术特征，使燃烬室内的可燃物彻底燃烬；由于采用了二次风进口、三次风进口沿炉膛内壁切向设置的技术特征，一方面起到对煤气和可燃微粒的搅拌作用，有利于煤气和可燃微粒的充分燃烧，另一方面可延长烟气在炉膛内的停留时间，使水管受热面最大限度的吸收烟气的热能，既降低了排烟温度，又降低了排烟中的二氧化硫的排放浓度及烟气黑度，使排放达国家标准：GB13271《锅炉大气污染物排放标准》中对二类区的要求；由于采用了在水管对流管束两侧与炉膛内壁的间隙处，设有封堵炉墙的技术特征，防止烟气从水管对流管束两侧与炉膛内壁的间隙排出，造成烟气短路，用炉墙限定烟气的行走路线，提高了本实用新型的立式煤气化节能锅炉的能量利用效率，降低了排烟温度。Beneficial effects: the vertical coal gasification energy-saving boiler of the present utility model has a furnace arch with holes in the furnace, which limits the rapid discharge of flue gas, increases the residence time of flue gas in the furnace, and improves the temperature of the furnace. At the same time, the furnace The increase of temperature is also conducive to the full combustion of fuel, so that the fuel of the vertical coal gasification energy-saving boiler of the utility model is completely burned, the thermal efficiency is high, and the energy-saving effect is good; The technical feature of the secondary air inlet connected to the secondary air supply pipe on the furnace wall provides sufficient oxygen for the combustion of the fuel and makes the combustion of the fuel more thorough; The technical characteristics of the tertiary air inlet connected to the tertiary air supply pipe make the combustibles in the combustion chamber completely burnt; due to the adoption of the technical characteristics of the secondary air inlet and the tertiary air inlet arranged tangentially along the inner wall of the furnace, on the one hand, it plays a role The stirring effect of gas and combustible particles is conducive to the full combustion of gas and combustible particles. On the other hand, it can prolong the residence time of flue gas in the furnace, so that the heating surface of the water pipe can absorb the heat energy of flue gas to the maximum extent, which not only reduces the smoke exhaust. The temperature also reduces the emission concentration of sulfur dioxide and the blackness of the flue gas in the flue gas, so that the emission meets the national standard: the requirements for the second-class area in the GB13271 "Emission Standard of Air Pollutants for Boilers"; The gap between the side and the inner wall of the furnace is equipped with the technical feature of sealing the furnace wall to prevent the flue gas from being discharged from the gap between the two sides of the convection tube bundle of the water pipe and the inner wall of the furnace, causing a short circuit of the flue gas. The furnace wall is used to limit the walking route of the flue gas and improve The energy utilization efficiency of the vertical coal gasification energy-saving boiler of the utility model is improved, and the exhaust gas temperature is reduced.
