A second jacket chamber 74 having a second hot water jacket 75 is provided on the top wall portion and the peripheral wall portion, and is connected to the jacket chamber 65 by a connecting pipe 73, and a chimney 76 is erected continuously from the inner cylinder 72. The second hot water jacket 75 is provided with a steam vent 78. Moreover, although the inner cylinder 72 is formed with a refractory material, it can be replaced with a structure in which warm water is stored therein. In that case, as shown by the imaginary line of FIG. 2, it connects with the hot water pipe 67 (or 2nd hot water jacket 75) with the connection pipe 75a.

  The second hot water jacket 75 communicates with the first hot water jacket 66 through a water passage 73a formed in the peripheral wall portion of the connection pipe 73, but is configured so as to be independent of each other and used as a hot water boiler. You can also The chimney 76 is provided with an air pipe 77 communicating with the forced fan 63, and air is supplied from the forced fan 63. A discharge port 79 for taking out ash is provided at the lower end of the dust collection chamber 71.

  The fuel supply mechanism unit 80 is provided adjacent to the combustion mechanism unit 60, the metering supply unit 81 storing the wood particulate fuel P is provided with a rotary screw 84 in the transport pipe 83, and the wood particulate material inlet 62 is provided. A screw conveyor 82 that communicates is provided, and the wood particulate fuel P of the quantitative feeder 81 is automatically supplied to the wood particulate inlet 62.

In FIG. 2, reference numeral 97 denotes a burner fan unit.

  A float 55 floating on the water surface in the water tank 54 is disposed at the outlet of the water pipe 52 connected to the upper side wall of the water tank 54, and a valve that closes the outlet of the water pipe 52 when the float 55 rises to a specified water level. 56 is provided to constitute a cis tank apparatus 53. The lower part of the cis tank device 53 is connected to the upper part of the first hot water jacket 66 through a water pipe 57. A drain pipe 58 having a cock 59 is connected to the lower side wall of the first hot water jacket 66. The position and structure of the cis tank device 53 are not limited to those shown in FIGS.

  The hot water boiler facility 50 operates as follows. After the wood particulates are put into the combustion chamber 61 and burned by the burner 68, the necessary amount of wood particulate fuel P is automatically supplied from the fuel supply mechanism 80. This supply can be easily performed because the wood particulate fuel P stored in the quantitative supply unit 81 is automatically conveyed by the screw in the conveyance pipe 83 continuously and appropriately.

  At this time, air is supplied from the forced fan 63 to the combustion chamber 61 to accelerate the combustion. Since this combustion chamber 61 is cylindrical, the wood particulate fuel P is completely burned while being moved along the peripheral wall together with air and being supplied with abundant air. By this combustion, the warm water in the first warm water jacket 66 is effectively heated.

  The warm air and dust generated in the combustion chamber 61 reach the dust collecting mechanism portion 70 through the connecting pipe 73, and then fall into the lower dust collecting chamber 71 by hitting the inner cylinder 72. Therefore, it is not released into the atmosphere through the chimney 76 as it is. In addition, the wood particulate fuel P that has not been burned completely burns in the dust collecting chamber 71. The warm water of the second jacket is heated by the heat and warm air at this time. The ash accumulated in the dust collecting chamber 71 is taken out from the discharge port 79.

  Hot water in the first hot water jacket 66 and the second hot water jacket 75 is conveyed to the hot water storage chamber 92 through the connection pipe 91. The hot water is further heated by a heater 93 as necessary, and then supplied by a pump 94 to a heated facility Q such as a greenhouse, a building, or a device having a structure requiring heating.

Yes. As a result, the amount of hot water is increased so that abundant hot water can be supplied to the heated facility Q. This hot water can be used for heating a building in addition to a greenhouse.

  FIG. 3 shows a second embodiment of the hot water boiler facility 50 according to the present invention. The feature of this hot water boiler facility 50 is that the combustion mechanism 60 is provided with a first once-through boiler 66A, and the dust collection mechanism 70 is provided with a second once-through boiler 75A. Along with this, a safety valve 95 and a water level gauge 96 are provided. Other components are the same as those in the first embodiment.

  A once-through boiler pumps water from one end of a long pipe and is heated, evaporated and heated in the middle, and is sent out as heated steam from the other end. It has the feature of being easy.

  This hot water boiler equipment supplies the steam generated in the first through-flow boiler 66A and the second through-flow boiler 75A to the heated equipment Q via the communication mechanism 90, and warms the heated equipment Q with the heat of the steam. It is used for Thereby, the heat which generate | occur | produces when burning a wooden granular material can be utilized effectively, without discarding.

Moreover, the hot water boiler equipment 50 which concerns on above-described 1st Embodiment and 2nd Embodiment has the following characteristics.
(A) Since the combustion mechanism section 60 and the dust collection mechanism section 70 are of a so-called two-cylinder type, they can be easily and effectively used, for example, by supplying hot water and steam from each mechanism section to a plurality of facilities.
(B) By using wood particulates as the wood particulate fuel P, the temperature of the combustion mechanism 60 and the dust collection mechanism 70 can be raised in a short time. If the combustion chamber 61 and the dust collection chamber 71 are substantially cylindrical, the temperature rise time can be advanced by 30% or more compared to the rectangular tube type.
(C) Since the combustion chamber 61 and the dust collection chamber 71 are cylindrical, the wood particulate fuel P swirls along its inner peripheral surface, and the residence time in the combustion chamber 61 and the like becomes longer. Accordingly, the combustion chamber 61 and the like are easily burned, and are likely to become high temperature in a short time. Furthermore, the amount of fuel used can be reduced.
(D) Since air is supplied from the forced fan 63, the entire combustion chamber 61 can be heated at a stretch. Moreover, the amount of ash can be reduced.
(E) When using a once-through boiler, steam can also be used. The once-through boiler uses steam, but since it is small in size, it does not require qualification and is easy to handle. Further, in the case of the hot water jackets 66 and 75, since the pressure is low in the present invention, no qualification is required and the handling thereof is easy.
(F) By appropriately increasing the number of hot water pipes, the heat transfer area increases and the amount of hot water generated increases. Therefore, the use of fuel is reduced and the hot water boiler is also downsized.
(G) Since some fuels have a high water content, waste heat is used to blow into the combustion chamber to increase calories.
(H) Further, waste heat is supplied to the quantitative silo to dry the chip.
(I) Since the combustion mechanism 60, the dust collecting mechanism 70, and the fuel supply unit 80 are arranged on the same concrete floor 51, the construction is easy and the operation of the facility is easily checked.

  The hot water boiler equipment according to the present invention is also optimal for heating equipment for other purposes.
