Abstract

La presente invención se relaciona con una caldera de lecho fluido circulante de presión supercrítica con superficie de transferencia de calor por evaporación de doble paso, que consiste de un cabezal importado del panel descendente de pared de agua que se conecta con el cabezal de la salida de la superficie de enfriamiento de la pared del horno, un panel descendente de pared de agua que se conecta con el cabezal importado del panel descendente de pared de agua, un cabezal de conexión del panel de pared de agua que se conecta con el panel descendente de pared de agua, un panel de elevación de pared de agua que se conecta con el cabezal de conexión del panel de pared de agua, un cabezal de la salida del panel de elevación de pared de agua que se conecta con el panel de elevación de pared de agua; El panel descendente de pared de agua y el panel de elevación de pared de agua están configurados en doble paso. El modo de configuración de doble paso hace que el cabezal de la salida del horno y el cabezal importado del panel descendente de pared de agua se configuren en la parte superior del horno, acorta la longitud de la conexión de tuberías, reduce el área de transferencia de calor de la pared enfriada por agua en el horno, y disminuye la altura del horno.The present invention relates to a supercritical pressure circulating fluid bed boiler with double pass evaporation heat transfer surface, which consists of a head imported from the descending water wall panel that is connected to the outlet head of the cooling surface of the furnace wall, a descending water wall panel that connects with the imported head of the water wall descending panel, a connecting head of the water wall panel that connects with the descending panel of water wall, a water wall lift panel that connects to the water wall panel connection head, a water wall lift panel outlet head that connects to the wall lift panel of water; The descending water wall panel and the water wall lifting panel are configured in double pass. The double-pass configuration mode causes the furnace outlet head and the imported head of the water wall down panel to be configured at the top of the oven, shortens the length of the pipe connection, reduces the transfer area of heat from the wall cooled by water in the oven, and decreases the height of the oven.
