Description
1 Изобретение относитс к области сжигани топлива и может быть использовано на тепловых электростан ци х. Целью изобретени вл етс повы шение экономичности путем снижени недожига. На чертеже: схематически изображено устройство дл осуществлени способа сжигани низкосортной угол ной пыли, продольный разрез . Устройство содержит топку 1, в нижней части которой в зоне сжигани размещена пылеугольна горелка 2, а в верхней части в зоне дожигани - кольцева перфорированна труба 3 подвода водорода . Топка 1 снабжена радиационньпу1й и конвективными поверхност ми нагрева 4 и 5. Труба 3 дл подвода водорода соединена с газгольдером через дозатор-прерыватель 7. Горел 12 ка 2 соединена с газгольдером 8 через дозатор-прерыватель 9. Способ сжигани низкосортной угольной пыли осуществл етс следующим образом. Через горелку 2 в зону сжигани топки 1 осуществл етс пульсирующа подача азросмеси совместно с пульсирующим потоком кислорода. Аэросмесь в зоне сжигани сгорает , а дымовые газы с несгоревшими частичками угл подымаютс в верхнюю часть топки 1 в зону дожигани , куда через трубу 3 пульсирующим потоком вводитс водород. Пульсационна подача кислорода осуществл етс с частотой, синхронной по времени с периодом активного горени угольной пыли в факеле. Кислород и водород в зоне дожигани образуют с углеродом топлива горючие углеводороды и окислы, способствующие снижению недожога.1 The invention relates to the field of fuel combustion and can be used in thermal power plants. The aim of the invention is to improve the economy by reducing underburning. In the drawing: schematically shows a device for carrying out the method of burning low-grade coal dust, a longitudinal section. The device contains a furnace 1, in the lower part of which a pulverized coal burner 2 is located in the combustion zone, and in the upper part in the afterburning zone - a circular perforated tube 3 of hydrogen supply. The furnace 1 is equipped with radiating and convective heating surfaces 4 and 5. A pipe 3 for supplying hydrogen is connected to a gas tank through a metering interrupter 7. A burner 12 2 is connected to a gas tank 8 via a metering interrupter 9. The method of burning low-grade coal dust is as follows . Through the burner 2 into the combustion zone of the furnace 1, a pulsating feed of the mixture is carried out together with a pulsating stream of oxygen. The aerosol in the combustion zone burns, and the flue gases with unburned coal particles rise in the upper part of the furnace 1 into the afterburning zone, where hydrogen is introduced through a pipe 3 in a pulsating flow. The pulsation supply of oxygen is carried out at a frequency synchronous in time with the period of active burning of coal dust in the flare. Oxygen and hydrogen in the afterburning zone form combustible hydrocarbons and oxides with the carbon of the fuel to reduce the underburning.
