Abstract
The invention discloses a large-scale high efficiency three-waste boiler combustion chamber. A film-type water-cooling wall is arranged on the top of the combustion chamber. A fire resistant casting material is coated on the outer side of the combustion chamber. The middle part of the combustion chamber is a cylindrical steel housing. Firebricks are coated on the inner side of the combustion chamber. The firebricks have a heat storing function. A barrier wall water cooling unit is arranged on the inner side of the firebricks. Another barrier wall water cooling unit is arranged at the center of the combustion chamber. The barrier wall water cooling units are heated from the two sides, and the evaporation capacity of the water cooling units takes 2/3 of that of the whole boiler. The central water cooling unit carries out water circulation separately, such that maintenance is convenient to carry out. A rectangular separate-chamber air distribution boiler bottom is arranged on the bottom of the combustion chamber. The rectangular boiler bottom is divided into 4 combustion zones, wherein the structure is beneficial for coal distribution, air distribution and slag discharging. Four feeding pipes and four spark lighters respectively penetrate into the four rectangular air distribution chambers. The bottom of the combustion chamber is provided with a slag discharging port, such that a linear arrangement is formed. Waste slag and waste gas are combusted in the combustion chamber, such that high-temperature flue gas is produced. The high-temperature flue gas is delivered from the combustion chamber into a cyclone separator, and large particles are separated from the flue gas in the cyclone separator. The large particles are delivered back to the combustion chamber to be combusted, until the carbon content in the boiler bottom residual slag is reduced to below 1%.
