Abstract

PURPOSE:To lower the production cost and running cost, by heating a circulating pump, a condenser, a turbine and a steam generating section arranged in a combustion chamber using a combusted gas in the combustion chamber. CONSTITUTION:A steam generating section 2, a turbine 3, a condenser 4 and a circulating pump 5 are arranged in a combustion chamber 1. A fluid is heated in the steam generating section 2 to produce steam, and a power is obtained by the steam generated in the turbine 3. The steam leaving the turbine 3 is cooled in the condenser 4 to be changed to liquid. When it is required to restart the plant, since the steam generating section 2, the turbine 3, the condenser 4 and the circulating pump 5 are preheated by the combusted gas from the combustion chamber 1, while extra facility, fuel or the like for preheating are not required. Thus, the production cost and the running cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam power plant in which a combustion chamber, a steam generating section, a turbine, a condenser, etc. (911 units including one or more reservoirs) are used as one operating unit.

A conventional device is shown in FIG. 1, and its outline will be explained below.

In FIG. 1, reference numeral 01 is a combustion chamber that burns heavy oil, coal, natural gas, etc. to generate high-temperature combustion gas. 02 is a steam generating section that heats liquid to generate steam. Reference numeral 03 denotes a turbine, which obtains power from the steam generated in the steam generating section 02. A condenser 04 cools the steam exiting the turbine 03 and turns it into liquid. 05 is a circulating Bonoff, and the liquid is r)

When the melting point of the working medium is above the normal range (a sound of ・, when the driving force 1 is stopped, the operation is high in each part of the piping), 1. Body is 0; There is.
The long places are the distribution i'-i part: l;-, 1, the heater 1' () 3, the condenser 04, and the circulation bonder () 5 outside the combustion chamber 01.

Therefore, the equipment for preheating (+iii and the use of energy:
If li becomes large and the cost is high < t+,
do.

The present invention has been made in an attempt to eliminate the drawbacks of the conventional example, and has made the piping part and the gauze machine in an innovative manner.
When heating a moving medium above its freezing point, use combustion gas for the sole purpose of heating or preheating.
The purpose of this invention is to provide a high melting point working medium steam power plant in which the use of energy and energy is unreliable, and is characterized in that the steam generating section, turbine and condenser are heated with combustion gas.

It can be applied to a steam power plant in which the body is a working sand body, a 23 IC body or a three-fluid steam power plant 11'i in which the cycle is a topping cycle.

Next, a preferred embodiment of the present invention will be described in detail with reference to FIG.

In the figure, 1 is a combustion chamber that burns heavy oil, coal, and natural gas to generate high-temperature combustion gas. Inside, a steam generator, turbine, condenser, and circulation pump are arranged differently from conventional examples. will be established.

2 is a steam generating section that heats liquid and generates steam. :
Reference numeral 3 denotes a turbine, which generates power using the steam generated in the steam generating section 2. 4 is a condenser that cools the steam leaving the turbine 3 and turns it into liquid. 5 is a circulation pump that circulates the liquid. However, if natural circulation is possible due to the arrangement of the steam engine 2, turbine 3, and condenser 4,
No longer needed.

The combustion residue flows as shown by the broken line in the figure.
