Title: Combustion device
Inventor: YAMAZAKI TADASHI
IPC: F23D11/40
Filed: 1994-05-31
Abstract: PURPOSE:To reduce an amount of CO generated during low combustion and an amount of NOx during high combustion. CONSTITUTION:A combustion chamber is formed in such a manner that secondary air is fed from an air chamber 8 in a burner case 1 to a space between a combustion cylinder 21 and an earth ring 19 through a first passage 22. The first passage 22 is horizontally formed and an opening 20 is formed in the earth ring 19. Thus, in the combustion device, since secondary air is throttled by the first passage 22 and a direction is changed to a horizontal direction to reduce a velocity of flow, during low combustion, an air amount optimum to a low combustion flame amount is inputted through the opening 20 of the earth ring 19. Since, during high combustion, a flame amount is high and a pressure is high, an air amount is not so much inputted to a flame root part but inputted to the tip part of flame to complete combustion, and the generation of CO and NOx is suppressed.

IPC: G21C9/016
Filed: 1993-05-20
Abstract: PURPOSE: To prevent progress to a floor, and prevent soil pollution in the vicinity of a reactor core by suddenly cooling a melted reactor core falling by an accident. CONSTITUTION: When a reactor core in a vessel 1 melts and falls by an accident, first of all, a silica concrete layer 8 of a heat absorbing body is disrupted, but since a refractory concrete layer 7 cannot be disrupted, it enters an empty clearance 5. Next, this melt is slowly lowered by reducing speed by a partition wall 4 after viscosity is significantly increased by the cooling action of water flowing in a coolant passage 6. In this case, the passage 6 is connected to a coolant source 11 existing in a high position by a pipe 10, and its opposite side is connected to a discharge port 13 to discharge steam generated by a temperature rise. Therefore, water of a coolant is extremely naturally circulated, and solidifies a melted reactor core material.  In this way, a melted reactor core falling material is largely decelerated, and is solidified before reaching a floor 3, and soil pollution is prevented.
