The multipurpose boiler comprises: a pressurizing means to generate a high pressure by pressurizing a working fluid circulating a system of a closed circuit using a pressurizing pump (10), and to move the high pressure working fluid to an evaporator (20); a heating means to receive the high pressure working fluid by the pressurizing means and to heat and pass the same through the evaporator (20) having a spiral heating pipe, and to transfer the high temperature and high pressure working fluid into an expander (30); an expansion and power generation means to receive the high temperature and high pressure working fluid, to expand the same into a high temperature and high pressure vapor in the expander (30), and to supply the same to a power generator (40) installed with a turbine to generate power; and a hot water and heating water providing means which sends a vapor state working fluid used for the power generation into a condenser (50) having a spiral pipe to change the working fluid into a liquid state and transfers heat energy provided in the above process to a hot water pipe (51) and a heating water pipe (52) inside the condenser (50) in order to provide hot water and heating water.

Description

Objective boiler system using ORC}

The present invention relates to a multi-purpose boiler using an oar seed system, and more particularly, to a multi-purpose boiler using an oar seed system capable of providing hot water and heating water while generating power.

Korea's electric power demand has been steadily and explosively increasing due to income level improvement and information technology development.

Korea is the only country in the world where the electricity rate is lower than that of primary energy, which is the secondary energy, Korea is the only country in the world. GHG emissions to GDP are the highest in the world. Effective use and supply of energy is inevitable .

Distributed power generation has emerged as a way to realize efficient energy production (consumption) policies and to cope with the rapid increase in electricity demand in real time.

As one of these distributed development policies, there is an urgent need for an ORC (Organic Rankine Cycle) power generation system using a variety of medium- and low-temperature heat sources that have been treated as waste heat.

Therefore, it is urgent to develop a boiler which can combine the OAL power generation system with a boiler to provide hot water, heating, and power generation.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above conventional problems, and it is an object of the present invention to provide a boiler system which combines a Rankine cycle as a basic cycle of a thermal power generation system and an organic material other than water as a working fluid, And to provide a multi-purpose boiler using an oar system that is environmentally friendly, efficient, and cost-effective.

In order to achieve the above object, the present invention provides a method of operating a system constituted by a closed circuit by pressurizing a working fluid circulating through a system using a pressurizing pump (10) to generate a high pressure and moving a high pressure working fluid to an evaporator Pressure means;

Heating means for transferring the high-pressure working fluid to the inflator (30) by passing the high-pressure working fluid through the evaporator (20) heated by the pressurizing means and forming a helical heating tube;

Expanding and generating means for expanding the high-temperature and high-pressure working fluid from the inflator 30 to the high-temperature and high-pressure steam and supplying the expanded high-pressure and high-pressure working fluid to the turbine-

The working fluid in the gaseous state after being used for power generation is sent to the condenser 50 in which the spiral tube is constituted and is changed to the liquid state and the heat energy generated in the process is transferred to the hot water pipe 51 and the heating pipe (52) for supplying hot water and heating water; .

On the other hand, the working fluid includes using an organic material other than water.

The multi-purpose boiler using the oar seeding system according to the present invention is advantageous in that it can provide hot water and heating water and can generate electricity, thereby being eco-friendly, efficient and cost-saving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In the drawings, the same components are denoted by the same reference numerals throughout the drawings, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted.

The boiler according to the present invention can provide power generation, hot water and heating water by combining a boiler system with an organic rank cycle (organic Rankine cycle) system.

Referring to the drawings, Rankine Cycle (1) has cycles of pressurization, heating and evaporation, expansion, and condensation as basic cycles of thermal power generation. In the present invention, the working fluid used in the Rankine cycle (1) is a specific organic material (refrigerant) instead of water.

The multi-purpose boiler using the oar seeding system according to the present invention comprises pressurizing means, heating means, expansion and power generating means, hot water and heating water supply means.

The pressurizing means pressurizes the working fluid circulating through the system constituted by the closed circuit by means of the pressurizing pump (10) to generate a high pressure and move the high pressure working fluid to the evaporator (20).

The heating means receives the working fluid of a high pressure by the pressurizing means and heats the heated working fluid to pass through the evaporator 20 constituted by the helical heating tube to move the high temperature and high pressure working fluid to the inflator 30.

The power generating means receives the high-temperature and high-pressure working fluid, expands the high-temperature and high-pressure working fluid from the inflator 30 to the generator 40 provided with the turbine, and produces electricity.

In addition, the electricity thus generated is stored in a capacitor (not shown), and DC is changed to AC by an inverter (not shown).

The hot water and the hot water supply means are used for power generation and then the working fluid in a gaseous state is sent to the condenser 50 in which the spiral tube is constituted to change into the liquid state and the heat energy generated in the process is supplied to the hot water Heat is conducted to the pipe 51 and the heating pipe 52 to provide hot water and heating water.

Therefore, according to the present invention, a Rankine Cycle (1), which is a basic cycle of thermal power generation, is combined with a boiler system and an organic material other than water is used as a working fluid to provide hot water and heating water, The present invention is to provide a multi-purpose boiler using the O-Se system which is cost-effective, efficient and cost-effective.
