Technical field
The present invention relates to energy-conserving and emission-cutting technology and equipment, be specifically related to a kind of novel energy-efficient overheated boiler.
Technical background
Normal conditions, arrange superheater in boiler, and its Main Function saturated vapor self-produced for boiler is carried out heating and overheated.
At present, waste heat recovery with utilize the quantity of steam that produces huge especially, but because of most waste heat heat source temperature limited, the afterheat steam temperature produced is lower, cause the power of afterheat steam and Generation Rate lower.
How improving afterheat steam temperature, improve power and the Generation Rate of unit afterheat steam amount, and improve the thermal efficiency and the efficiency of investment of waste heat power and power generation project, is current energy-conserving and emission-cutting technology and equipment urgent problem.
Summary of the invention
In order to overcome the deficiency of existing energy-conserving and emission-cutting technology and boiler equipment, the present invention is directed to power and the lower phenomenon of generating efficiency of afterheat steam and Low Temperature Steam, by integrating the thermodynamics such as the effective rate of utilization of device of working medium liquid gas phase transition characteristic and thermal source heat energy, innovate the overheated boiler of a kind of novel high-efficiency and energy-saving.
A kind of novel energy-efficient overheated boiler of the present invention, the afterheat steam that outside mainly inputs by first superheater and Low Temperature Steam carry out heating and overheated; It two is heat exchange demands that thermal source heat energy mainly meets superheater; Its three be by superheater after the integrated waste heat boiler of flue gas produce saturated vapor and carry out combined cycle, realize the target of energy-saving and emission-reduction.
For solving the problem of prior art, the technical solution used in the present invention is:
A novel energy-efficient overheated boiler, comprises super-heater exit case, superheater, superheater import header, input afterheat steam and Low Temperature Steam pipe, saturated steam pipe, drum, tedge, down-comer, evaporimeter, hot-water line, economizer and boiler feed pipe.Described super-heater exit case is connected with superheater; Described superheater is connected with superheater import header; Described superheater import header is connected with saturated vapor pipeline with input afterheat steam and Low Temperature Steam pipe; Described saturated steam pipe is connected with drum; Described drum is connected with tedge, down-comer and hot-water line; Described tedge is connected with evaporimeter with down-comer; Described hot-water line is connected with economizer; Described economizer is connected with feed pipe.
Further, described a kind of novel energy-efficient overheated boiler, can arrange separate unit cover and overlap superheater with multiple stage, therefore has and singly presses through the multiple constrained input methods of operation such as hot and multiple pressure is overheated.
Further, described a kind of novel energy-efficient overheated boiler, has Natural Circulation and forced circulation two kinds of endless form.
Further, described a kind of novel energy-efficient overheated boiler, has vertical and horizontal two kinds of arrangements.
Further, described a kind of novel energy-efficient overheated boiler, selects high, medium and low voltage and high temperature, middle temperature according to actual needs voluntarily.
Beneficial effect of the present invention: the first mainly solves the high-efficiency heating of afterheat steam and Low Temperature Steam and overheated, make overheated after the power of unit quantity of steam and Generation Rate significantly improve; It two is that thermal source heat energy and steam are carried out heat exchange, avoids and the latent heat of vaporization decreasing water, therefore realizes the power and the Generation Rate that significantly improve thermal source unit thermal energy; Three especially a large amount of saturated vapors in steel industry production process are overheated tremendous potential and effect solving for it.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the overheated boiler of novel high-efficiency and energy-saving of the present invention.
Wherein super-heater exit case 1, superheater 2, superheater import header 3, input afterheat steam and Low Temperature Steam pipe 4, saturated steam pipe 5, drum 6, tedge 7, down-comer 8, evaporimeter 9, hot-water line 10, economizer 11, boiler feed pipe 12.
Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with specific embodiment, the present invention is described in further detail.
1 couple of the present invention is further analyzed with reference to the accompanying drawings below:
An energy-conservation overheated boiler novel as shown in Figure 1, boiler combustion produces or the outside high temperature heat source flue gas inputted, and successively after the heat exchanges such as superheater 2, evaporimeter 9 and economizer 11, is discharged by economizer 11 afterbody; The afterheat steam of outside input and Low Temperature Steam are through input afterheat steam and Low Temperature Steam pipe 4, and the saturated vapor that drum 6 exports is through saturated steam pipe 5, below superheater import header 3 is jointly inputted, and be delivered to superheater 2, again after superheater 2 with the thermal source flue gas heat exchange passed through, the superheated steam produced is exported by super-heater exit case 1; Saturation water in drum 6, evaporimeter 9 is inputed to through down-comer 8, again after evaporator 9 with the thermal source flue gas heat exchange passed through, input to drum 6 by tedge 7 and carry out carbonated drink separation, the saturated vapor produced inputs to superheater import header 3 by saturated steam pipe 5; Boiler feedwater inputs to economizer 11 through boiler feed pipe 12, then after economizer 11 with the thermal source flue gas heat exchange passed through, the hot water produced inputs to drum 6 by hot-water line 10.Above-mentioned continuous operation process is exactly operation and the use of the overheated boiler of novel high-efficiency and energy-saving of the present invention.
Boiler main of the present invention will solve the high-efficiency heating of afterheat steam and Low Temperature Steam and overheated, make overheated after the power of unit quantity of steam and Generation Rate significantly improve; Thermal source heat energy and steam are carried out heat exchange, avoids and the latent heat of vaporization decreasing water, therefore realize the power and the Generation Rate that significantly improve thermal source unit thermal energy; Solving, a large amount of saturated vapors in steel industry production process are overheated tremendous potential and effect.
The explanation of above embodiment is just for helping method and the core concept thereof of understanding the application; Meanwhile, for one of ordinary skill in the art, according to the thought of the application, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction to the application.
