Description

No-pressure hot water boiler {nopressure hot-water heating boiler}

The present invention relates to a pressureless irrigation boiler used when supplying a large amount of hot water, and more particularly, to install a vertical tube, a horizontal tube, and a gas flow breaker in multiple combustion chambers in which combustion gas is communicated to the boiler body. By slowing down the combustion heat and combustion gas and controlling the flow, it is possible to minimize the heat loss and increase the thermal efficiency. Also, by fastening the support in the center of the heat exchanger, deformation during expansion due to the temperature rise of the heat exchanger can be achieved. It is designed to extend the life of the heat exchanger by preventing.

In general, a boiler burns fuel such as petroleum, coal, gas, and transmits the heat of combustion to water to generate steam, and is a device for boiling water in order to send hot water to a home heating facility or a bath.

The boiler uses a typical hot water boiler because it needs to supply a large amount of hot water in a large group facility such as a bathroom and a hotel.

However, since the hot water boiler needs to supply a large amount of water, the capstone and corrosion are generated by impurities such as calcium salt and dissolved oxygen contained in the water supply, thereby causing problems such as lowering the thermal efficiency of the boiler and shortening the lifespan. Doing.

In order to solve the above problems, the water in the boiler maintained at no pressure is circulated up and down in the liquid chamber as the burner burns, and is heated to a temperature below the boiling point, and the heat exchanger is heated by steam generated from the heated water. Pressureless hot water boilers are widely used.

In addition, the current pressureless hot water boiler has a plurality of combustion chambers connected to communicate the heat of combustion generated from the burner inside the expansion tank filled with irrigation water, horizontal pipes through which the water flows through the combustion chamber horizontally, and at both ends. A water supply port and a return port are attached to each other so as to form a heat exchanger to supply hot water by the steam of the water, thereby increasing the thermal efficiency.

However, the pressureless irrigation-type boiler has a problem that heat loss occurs because horizontal pipes horizontally penetrated in the combustion chamber are regularly formed so that the heat of combustion generated in the burner is circulated and discharged at a high speed.

In addition, deformation of the heat exchanger, such as expansion of the heat exchanger occurs in the water of the irrigation, there is a problem of frequent failures and shortening the life of the heat exchanger.

Therefore, the present invention for solving the above problems is provided with an irregular vertical tube and a horizontal tube in a plurality of combustion chambers connected to communicate the heat of combustion in the boiler body, and by installing a gas flow wave plate on the side to reduce the heat of combustion And by controlling the flow, not only can minimize the heat loss of the discharged combustion heat, but also increase the thermal efficiency, by fastening the support in the center of the heat exchanger, by preventing the deformation during expansion due to the temperature rise of the heat exchanger This can extend the life of the heat exchanger.
