Tswv yim chav turbines tuaj nyob rau hauv tag nrho cov duab thiab ntau thiab tsawg thiab tsim lub zog xws li ntawm ib lossis ob megawatts (kwv yees ib yam tso zis raws li ib qho cua turbine ) mus txog 1,000 megawatts lossis ntau dua (the tso zis los ntawm ib tug loj zog cog, sib npaug rau 500-1000 cua turbines ua haujlwm ntawm lub peev xwm puv).
Tsis tas li lo lus nug yog, pes tsawg lub chav turbine nqi?
Raws li qhia, ntsia tus nqi rau cov turbine / generator ntau ntawm kwv yees li $ 670 / kW txog $ 1, 140 / kW, nrog tus nqi ntawm ib kW hauv paus poob qis thaum muaj peev xwm nce. Cov turbine /generator tus nqi hauv Table 3 suav nrog chav turbine , generator, thiab generator tswj qhov system.
Qhov thib ob, vim li cas cov pa siv rau kev tsim hluav taws xob? Superheated chav Nws yog ib qho tseem ceeb vim hais tias nws ua rau kom cov efficiency ntawm boiler. Hauv tsim hluav taws xob kev lag luam nws ua haujlwm tseem ceeb ntxiv: "qhuav" lub chav . Nws yog ib qho tseem ceeb uas qhuav steam yog siv los tsim hluav taws xob vim cov dej ntws tuaj yeem ua rau lub cev puas tsuaj zog - tsim turbines.
Ua raws li qhov kev pom no, vim li cas chav ua haujlwm tig lub turbine?
Hauv cov ntsiab lus yooj yim, a chav turbine ua hauj lwm los ntawm kev siv lub tshav kub (gas, thee, nuclear, solar) kom sov dej mus rau qhov kub siab heev kom txog thaum nws hloov mus rau hauv chav . Lub peev xwm zog ntawm lub chav yog li ntawd tig mus rau hauv kinetic zog nyob rau hauv lub rotating turbine cov cov hniav.
Cov chav turbines cais li cas?
Chav turbines tuaj yeem yog cais nyob rau hauv ntau txoj kev (Elliot, 1989). Lawv tuaj yeem yog cais los ntawm lub voj voog thiab chav Cov xwm txheej xws li Rankine cycle, Rankine regenerative cycle, reheat cycle, condensing lossis noncondensing, thiab los ntawm tus lej thiab kev npaj ntawm turbine shafts thiab casings. Hla-compound chav turbine.

Tus nqi hluav taws xob hluav taws xob ntau npaum li cas hauv UK? Teb: Geothermal cov lus nug hauv UK feem ntau xa mus rau hauv av qhov cua sov. Cov tshuab hluav taws xob hauv av no raug nqi nruab nrab ntawm £ 10,000 txog £ 20,000 los yuav thiab nruab. Cov tswv tsev tseem yuav tsum suav rau cov nqi kev pabcuam txhua xyoo, uas tuaj yeem nyob ib puag ncig £ 300
Dab tsi yog kev siv hluav taws xob Yuav ua li cas kev lag luam tsim ntau hom kev siv hluav taws xob?
Kev siv hluav taws xob yog hais txog tus nqi lossis txiaj ntsig uas tus neeg siv khoom tau txais los ntawm kev sib pauv, raws li University of Delaware. Muaj plaub hom kev siv: daim ntawv, qhov chaw, sijhawm thiab muaj; ua ke, lawv pab tsim cov neeg siv khoom txaus siab
Nws raug nqi npaum li cas los tsim lub tshuab hluav taws xob hluav taws xob?
International Renewable Energy Agency (IRENA) tshaj tawm cov nqi peev nyiaj nruab nrab rau cov chaw tsim hluav taws xob loj loj nrog cov chaw cia khoom feem ntau los ntawm qis li $ 1,050 / kW mus txog li $ 7,650 / kW, thaum qhov ntau ntawm cov phiaj xwm me me yog nyob nruab nrab ntawm $ 1,300 / kW thiab $ 8,000 / kW

Cov nyiaj txuag hluav taws xob hluav taws xob txuag nyiaj ntau npaum li cas?
Cov naj npawb los ntawm US Environmental Protection Agency (EPA) qhia tias cov tswv tsev txuag tau 30-70% ntawm cov cua sov thiab 20-50% ntawm cov nqi cua txias los ntawm kev siv cov twj tso cua kub hauv av piv rau lwm cov tshuab pa. Qhov no txhais tau li ntawm $400 txog $1,500 txhua xyoo txuag nyiaj
