Description

Warm water supply system with perfusion hexagonal horizontal steam boiler

The present invention relates to a hot water supply system using a perfusion type hexagonal horizontal steam boiler, and more particularly, a hot water head is installed horizontally on the top of the water pipe to discharge the water inside the perfusion type hexagonal horizontal steam boiler to the outside. The present invention relates to a hot water supply system using a perfusion-type hexagonal horizontal steam boiler that uses steam and hot water at the same time by circulating water inside the hot water head with an external water tank to circulate the inside of the boiler.

In general, where a steam and hot water are used simultaneously, such as a bathroom, a boiler system for supplying steam and hot water is required. An example thereof will be described with reference to FIG. 1A.

1A is a system diagram illustrating a conventional steam and hot water supply boiler system for a bathroom.

The conventional steam supply boiler system includes a steam boiler 12 for heating water to generate steam, a head 14 for distributing and supplying steam generated from the steam boiler 12 to each sauna chamber 13, Condensed water tank 15 for condensing the waste steam generated in the sauna room 13, and a pump 16 for supplying the condensed water of the condensed water tank 15 to the steam boiler 12, the steam boiler The steam generated from (12) is used in the sauna room 13, and the waste steam generated in the sauna room 13 is circulated to the steam boiler 12 via the condensed water tank 15.

The hot water supply boiler system for the bath comprises a hot water tank 24 through which cold water introduced by the pump 22 is heated and discharged, and a hot water boiler 26 for heating cold water introduced into the hot water tank 24. Thus, the cold water introduced into the hot water tank 24 by the pump 22 is heated to supply hot water.

Meanwhile, in the conventional steam supply boiler system as described above, the internal structure of the steam boiler 12 is described below with reference to FIGS. Take a look.

FIG. 1B is a side cross-sectional view showing a once-through hexagonal horizontal steam boiler, and FIG. 1C is a front cross-sectional view showing a once-through hexagonal horizontal steam boiler, wherein the steam head 30 and the watering head 40 arranged horizontally in the upper and lower portions thereof. The water pipe 50 is arranged in a left / right symmetrical arrangement so as to be a hexagon in the whole, and the inner lower end portion and the outer upper end portion of the plurality of heat transfer fins 62, 64 having a center bent so that the combustion gas flows from the lower portion to the upper portion thereof. It is installed between the water pipe 50 symmetrically to open, and installed a fire-resistant and heat-resistant jacket (82, 84) at both ends of the steam head 30 and the watering head 40 to form a closed combustion furnace In addition, the burner 86 is installed through the upper side of the jacket 84, and the outer periphery and the gap of the heat transfer fin 62 so that the combustion gas discharged upward through the heat transfer fins 62 and 64 flows back to the bottom. It is formed to have a (92) and the combustion gas is discharged to the flue 94 at the bottom Covering the outer periphery of the components with a fire-resistant and heat-insulating cover 90 formed with a dust collecting chamber 96, the high-pressure washing tube 97 for washing in the upper portion between the cover 90 and the heat transfer fin 62 By installing this, the left and right widths of the boiler are independent of the length of the flame so that they are less restricted by the opening width of the boiler installation place.

However, in the conventional steam and hot water supply boiler system for the bath as described above, the steam supply system and the hot water supply system are separated, so if you want to obtain both hot water and steam steam boiler 12 and hot water boiler 26 Since there is a problem in that the fuel consumption and maintenance costs are increased because it must be driven separately, a hot water heater (not shown) supplied with a high temperature / high pressure steam from the head 14 to compensate for the above problems hot water tank The structure attached to (24) has been known, but in the case of a large-capacity boiler, a hot water heater (not shown) that receives high pressure steam is attached to the hot water tank 24 so that the hot water tank 24 itself is attached to the equipment inspection item. There was a problem that the installation and maintenance inspection is difficult.

Accordingly, a system for supplying hot water by circulating the water of the perfusion type hexagonal horizontal steam boiler 12 configured as described above to the outside is considered, but the conventional perfusion type steam boiler 12 as described above Since the irrigation water is not heated, it is impossible to supply hot water even if it is circulated. Since the irrigation water is already converted to steam at the top of the boiler, the irrigation water cannot be discharged. There was a problem that the equipment is difficult because the equipment.

The purpose of the present invention for solving the problems as described above is to improve the structure of the boiler by installing a hot water head horizontally on top of the water pipe so as to discharge the water inside the flow-through hexagonal horizontal steam boiler to the outside, It is to provide a hot water supply system using a perfusion-type hexagonal horizontal steam boiler that allows the use of steam and hot water at the same time by circulating the water inside the hot water head with the external water tank to circulate inside the boiler.
