摘要： PURPOSE:To adjust concentration of pulverized coal to a value suitable for combustion in a burner, by a method wherein an airtight quantitative coal supply device is provided underneath a cyclone separator and a T-shaped mixer is provided underneath the coal supply device. CONSTITUTION:Although pulverized coal pulverized by a mill 1 is carried out through either air or gas to be sent from a blower 8, the air or gas discharged from the upper part of a cyclone separator 2 and streamed through a flow path 15 in a ramified state is supplied to a T-shaped mixer 7. The pulverized coal separated by the cyclone separator 2 is sent out from underneath of the separator 2 by an airtight quantitative coal supply device 6 and supplied to the T- shaped mixer 7. As the quantitative coal supply device 6 can vary a supply quantity of the pulverized coal by varying the number of rotations, concentration of the pulverized coal to be supplied to a burner by passing through a flow path 17 is turned into a value optimum for combustion in the burner.

摘要： PURPOSE:To obtain the titled pulverized coal-air ratio adjusting device for adjusting the concentration of pulverized coal to a value adapted for the combustion in the burner by measuring the quantity of air or gas to be supplied to a mill and the quantity of air or a gas exhausted through an outlet port of a separator and to adjust the quantity thereof by a damper. CONSTITUTION:The quantity of air or gas of a high temperature supplied to a mill 1 is measured by a flow quantity meter 11 provided in a flow passage 8', the quantity of air or gas passing from the upper part of a cyclone separator 2 and discharged via a flow passage 10 is measured by a flow quantity meter 12 and the quantity of air or gas branched from the flow passage 10 and flowing through a flow passage 13 is measured by a flow quantity meter 14. The quantity of pulverized coal is obtained from the quantity of coal supplied to the mill 1 and the ratio A/C of the quantity of air (gas) carrying pulverized coal to the burner to the quantity of pulverized coal is sought. The quantity of air or gas to be supplied to the mill 1 through the flow passage 8 is controlled by actuating the damper 7 so that the ratio A/C assumes a predetermined value. The quantity of air or gas discharged through the flow passage 10 by actuating the damper 9. In this manner, the concentration of pulverized coal supplied from a T-shaped mixer 4' to the burner via a flow passage 15 assumes a value optimum for the combustion in the burner.

摘要： PURPOSE:To simplify the structure of a water-cooled wall and the duct of a combustion chamber to facilitate the manufacture thereof and to decrease the cost therefore by dividing two-stage combustion air holes of the combustion chamber into several parts and dividing and supplying two-stage combustion air from the air holes into the upstream and the downstream of combustion gas. CONSTITUTION:Several two-stage combustion air holes 3 are provided laterally at the upper part of an upermost burner 2 in a suitable distance. Respective lateral two-stage combustion air holes 3 are divided at the upper and lower parts, and divided air holes 3a and 3b have such a structure that the stream of two-stage combustion air assumes the forms shown by solid lines and oblique lines. By the multistage, two-stage combustion air holes 3, the two-stage combustion air can be divided and supplied to the upstream and the downstream of the combustion gas generated from the pulverized coal combustion by the burner 2 of a boiler combustion chamber 1, and reduction of NOx and C in the substantially same degree as the case of providing ordinary two-stage combustion air holes at the upper and lower stages can be effected.

摘要： PURPOSE:To allow the uniform mixing of flame with combustion gas inside a combustion chamber, by providing a swirl blade at the top end inside an air hole with freedom of orientation. CONSTITUTION:A swirl blade 4 is provided at the top end inside an air hole 1, the swirl balde 4 supported on the top end of hollow shaft 5 provided at the axis portion inside the air hole 1 so as to vary the orientation of swirl blade externally by means of swirl device provided inside the hollow shaft 5. Its swirling force is regulated by altering the orientation of swirl blade 4 externally by means of swirl device provided inside the hollow shaft 5. In this way, it becomes available to arbitrarily alter the outward spread of two-stage combustion air coming out of air hole, and thereby creating a circulation flow outside that portion and inside the two-stage combustion air.
