摘要： PROBLEM TO BE SOLVED: To provide a marine boiler structure, capable of reducing NOx level in combustion gas by suppressing a combustion gas high-temperature portion formed within a furnace by burning effectively using the space within the furnace. SOLUTION: The marine boiler structure includes two burners 3 installed in an upper portion of the furnace 2, and is configured so that combustion gas generated by burning in the burners 3 flows from the furnace 2 through a heat transfer tube group Ht on the downstream side thereof. The swirling directions of the burners 3 (arrows SL, SR) are set to different directions or clockwise and counterclockwise directions, and the burners 3 differed in swirling direction are combined and disposed so that flame is diffused to the whole body of the furnace 2.

摘要： PROBLEM TO BE SOLVED: To provide a device for calculating a heat flux of a furnace heat transfer tube capable of obtaining calculation results more precisely than a conventional one with less calculator resources.
SOLUTION: A device for calculating a heat flux of a boiler is equipped with plural groups of heat absorption panels forming a tertiary superheater and a secondary reheater downstream of a flow direction of combustion gas generated in a furnace. In this device, each one of lattice is produced to a flow path between a pair of heat absorption panels corresponding to the tertiary superheater and the secondary reheater in a separating direction (step 102). Numeric calculation formulae relating to heat transfer with flow rate and temperature of combustion gas adjacent to each heat absorption panel, and outer surface temperature of the heat absorption panel as variables are applied to each lattice, so that numeric calculation is repeated by using calculation results of the other lattice (step 106).

摘要： PROBLEM TO BE SOLVED: To reduce the number of divided elements as far as possible, to reduce the required time and the cost of a computation to a minimum and to hold a sufficient analytical accuracy by a method wherein a radiant-heat flow flux is computed by a radiation intensity obtained by creating simultaneous simple equaitons on the basis of the factor matrix and the constant vector of every element. SOLUTION: A scattering-establishment-data generation part 12 computes a scattering establishment function on the basis of required data from an input part 11 so as to be input to a scattering-establishment-data storage part 13. In addition, data from a radiation-factor-data generation part 14 is stored in a radiation-factor-data storage part 15. Then, an element division part 16 divides the element of an input gasification-furnance inside shape on the basis of an input from the input part 11 and on the basis of radiation factor data. Computed factor matrix data is stored in a storage part, and an element volume is stored in a storage part 18. A radiation- intensity computation part 19 computes a radiation intensity on the basis of radiation factor data, on the basis of factor matrix data and on the basis of the element volume. Then, in a radiant-heat-flow flux computing part 20, a radiant-heat flow flux is computed on the basis of the radiation intensity computed by the computing part 19.

摘要： PURPOSE:To ensure the same jetting velocity at the time of a low load as the one at the time of a high load and thereby to maintain excellent fuel properties at all times by enabling regulation of the area of a jet port of a fuel oil in accordance with a load. CONSTITUTION:A fuel oil 3 passes through a gap between a valve rod 6a and a spray casing 4a and is jetted into a combustor from a fuel oil jet port 5 formed by a cap 4b of a spray and the fore end part of the valve rod 6a. By a screw 6c provided in the main body 6b of a valve rod driving device, the rotating motion of a stepping motor 7a is changed into a reciprocating motion, the valve rod 6a is thereby made movable and the jet area of a jet port 5 of the fuel oil can be changed therewith freely. On the occasion, the area of the jet port is regulated constantly by a control device so that a pressure difference between the inside of the combustor and the inlet of a jetting unit be within a range set for a high load. At the time of a low load, the area of the fuel jet port 5 lessens with an advance of the valve rod 6a, a prescribed flow velocity is maintained not withstanding the reduction of a flow rate, and atomization of the fuel oil is ensured.

摘要： PURPOSE:To use a catalyst effectively and to obtain produced gas decomposed to a desired state inexpensively by separating a heatreceiving body to plural layers in the direction of gas stream and regulating an equivalent pore size or void of the heat receiving body at a heat radiating body side to a different value from that at a side separated from the heat radiating body. CONSTITUTION:A porous heat receiving body 4 deposited with a catalyst is separated into plural layers of heat receiving body 4a, 4b, 4c in a direction from an upstream side to a downstream side of a gas stream. The pore size of each heat receiving body 4a, 4b, 4c is arranged to be smallest in the heat receiving body 4a, somewhat larger in the heat receiving body 4b, and largest in the heat receiving body 4c, thus, the radiation absorbing capacity of the heat receiving body 4a is made larger than those of the heat receiving body 4b, 4c. As a result, the amt. of heat to be absorbed by the heat receiving body is increased at an inlet of feed gas 8, and the temp. of the heat receiving body 4a at the inlet of the feed gas 8 is elevated, so heating capacity for the feed gas 8 improved. By this constitution, the catalyst deposited to the heat receiving body 4 at the inlet of the feed gas 8 is used effectively, and produced gas decomposed to a desired state is obtd. inexpensively.
