The boiler door is a furnace door with an ash trough, including a round furnace door seat and a furnace door cover, which is characterized by a semicircular ash trough with a long furnace diameter nested in a round furnace door seat. The diameter of the semicircular ash tank is connected with the round steel, and the central point of the round steel is connected with the central point of the furnace door cover with a connecting rod. The length of the connecting rod is that the furnace door seat is aligned with the fire sealing hole on the furnace door cover, and the front end of the semicircular ash tank is aligned with the inner wall of the furnace, so that there is no coal ash pollution when changing coal, and the problem of lax fire sealing of the coal furnace is solved. The boiler door is simple in structure and convenient in use.
