Description

Boiler energy complexion device

The present invention is a boiler energy complexing device, in particular, the heat exchanger of the boiler by combining the use of fossil energy such as coal, oil, gas and electric energy to make a low cost midnight electricity usefully It relates to an energy complex device.

The energy supply required by heat exchangers in all current boilers is a single energy supply, ie electricity. gas. Oil. Only one type of coal has been adopted to consider thermal efficiency and economics.

On the other hand, it can be said that it is proportional to the cleanliness characteristics of the fuel considering only the energy source that can be used in the boiler, that is, the fuel economy. That's coal. Oil. gas. Economics are in order of electricity.

In Korea, where energy resources are fundamentally lacking, securing energy saving methods and measures is a very small concern in terms of national economy and environmental protection. Currently, KEPCO reserves a 3-4% reserve rate during the day. The reserve rate is 60% or more, and as the power plant construction (except hydroelectric power generation) is expanded, the reserve rate will increase, and the electricity cost of the late-night (from 10:00 pm to 8:00 am) electricity is almost one quarter lower than that of the daytime. It is already known that its use is inexpensive and its use is widely recommended.

On the other hand, in the past, electric boilers were used to use midnight electricity alone, which is significantly cheaper than daytime electricity costs, but in order to maintain heating during the daytime, a relatively large heat storage tank was installed and heat storage material was installed in the tank. The cost of additional equipment is high, such as the need to install latent heat on the floor of the heating, which reduces the utility of the residential space, while the heating efficiency is gradually reduced during the day, which is not currently used. It is true.

Therefore, the present inventors have applied the concept of the time zone to the current energy and analyze how to utilize the late-night electric energy that is discarded among the electric energy produced by KEPCO as a very low-cost energy resource. The invention was completed.

1 to 9 are exemplary views showing an embodiment of the present invention, Figures 1 to 3 is an example of applying the present invention to a gas boiler according to this example, the boiler 101 is heated by the gas burner 102 The heat exchanger 103 using water as a heat transfer medium is formed of a heat exchanger tube 104 zigzag-piped, and a plurality of fins (3) are formed on the outer circumferential surface of the heat exchanger tube 104 which is bent in multiple layers to widen the heat transfer area. 105 are attached.

According to the present invention, an electric heater 106 having a proper capacity is installed on the heat exchange path of the heat exchanger 103 so as to supply midnight electric energy. In this example, the electric heater 106 has a heating wire ( 107, which is a rod-shaped body fitted with two male and female assembling and supporting sockets 109, 110 and a watertight packing ring 111 having a tie 108 and a threaded portion in the bent end of the heat exchange tube 104. It is inserted and installed.

In addition, according to this example, the electric heater 106 is also provided with a threaded spiral means 112 on the outer peripheral surface of the rod-shaped body, which spirally extends the heat transfer area of the electric heater and on the heat exchange conduit. To form a vortex to increase the efficiency of heat exchange.

4 is an electric circuit diagram for explaining the electric apparatus of the present invention. According to the present invention, AC power supplied through a power line not shown in the drawing is connected to a timer through a power switch SW and a fuse. Supplied to (TIMER).

Therefore, in the Daily Timer (TIMER), which is turned on only at certain times of the day, the contact point (A) and the contact point (B) are connected and the relay (RY) is turned on at the time when the midnight electricity is supplied (20 o'clock to 08:00). As the electricity is supplied to the relay, the relay contact P short-circuits the contact between the contact C and the contact b to stop the operation of the solenoid drive unit SOL, which is supplied through the fuel supply line by the solenoid valve SOL-V. The supply of fuel to the gas or oil is cut off so that the heating by the fuel is stopped.

At the same time, the c contact and the a contact of the relay contact (P) is connected to be supplied simultaneously to the electric heater 106 is connected to a plurality of in parallel to heat the heating water flowing through the heat exchange tube by the heat generated by the heater.

On the other hand, because the timer (TIMER) is turned off during the day time zone other than the late night time and the contacts (A) and (C) are turned on so that electricity is not supplied to the relay (RY), the contact point c of the relay contact point P and the contact point b While on, power is supplied to the solenoid drive unit SOL to resume the supply of gas or oil which has been blocked by the solenoid valve SOL-V so that combustion is performed.

The present invention configured as described above operates the boiler 101 as a normal gas boiler using gas energy during the daytime zone, and then reaches a midnight time zone (10:00 pm to 8:00 am) when the relay contacts are solenoid by the operation of the timer. The electric heater 106 is heated by midnight electric energy as a result of interrupting the heat exchange by the gas burner 102 while shutting off the current supply to the valve to interrupt the heat exchange by the gas burner 102, and simultaneously connecting the relay contact to the electric heater side. The heat of the heat exchange medium medium in the heat exchanger tube 104 of the heat exchanger 103 may be heat-exchanged and heated by the electric energy of the heater 106 to be used as an electric boiler using low-cost late-night electric energy.

It is formed by the pipe 204, and the electric heater 206 is installed on the pipeline of the heat exchange tube 204, and the spiral means 212 for expanding the heat transfer area and forming the vortex is provided on the pipeline. In the present example, the electric heater is formed of a rod-shaped body provided with a spiral means on the outer circumferential surface and the rod-shaped body is inserted into the heat exchanger tube. 206 is used by inserting a plurality of insulators 213 on the outer circumferential surface of the coil body, and a spiral means 212 made of spiral grooves is provided on the outer circumference of the heat exchanger tube 204 to allow the helical means 212 to be inserted into the spiral groove of the spiral means 212. Coiled Is such that the electric energy into the conduit from the outer periphery of the stand pipe heat exchanger 204 so wound onto the heater group 206. The

In this example, as in the above example, the gas burner 202 is applied to the gas burner 202 in the daytime time, and used as a conventional gas boiler. In the late night time, the gas burner 202 is stopped and the electric heater 206 is applied. By applying electric energy, it is possible to use low-cost midnight electricity.
