The Step-up, Step-down trap…
This is the way the most energy systems in the world are built today – Electricity grids take the voltage all the way up to 11 KV (11000V), 33 KV (33000V) and 66 KV (66000V). Your home consumption may be at 230V (India) or 110 V (USA) and so on. But, we use a transformer next to the consumption point and step it down.
Same way, many companies run long steam lines or thermic fluid lines that are generated in a central boiler plant – at 150 Deg C to 250 Deg C. This high temperature steam/thermic fluid pipe is very similar to the high voltage grid.
But, the end use is usually at lower temperature levels. Much like our electricity – where our usage voltage is low. Say, metal pre-treatment is at 60-70 Deg C. Washing is at 50 Deg C and so on.
If we can interrupt it at lower temperature level and produce energy, why should we not do it?
That is what we have done in our Wheels India Padi installation. We stop the high temperature thermic fluid lines, and instead run the low temperature process using solar heaters that produce the requisite lower temperatures.
Mtego wa hatua juu, hatua chini ni njia ambayo mifumo ya nishati nyingi ulimwenguni imejengwa leo - mitandao ya umeme inachukua voltage hadi 11KV (11,000V), 33KV (33,000V) na 66KV (66,000V). Kwa mfano, umeme wa nyumbani unaweza kuwa 230V (India) au 110V (USA). Lakini, sisi kutumia transformer karibu na uhakika wa matumizi na hatua yake chini. Matofali ya mvuke wa joto, ambayo hutengenezwa katika kiwanda cha boiler ya kati, hutengenezwa kwa joto la 150 ° C hadi 250 ° C. Matofali haya ya mvuke wa joto la juu yanafanana sana na gridi ya voltaji ya juu. Lakini, matumizi ya mwisho ni kawaida katika viwango vya chini vya joto. Karibu kama umeme wetu <unk> ambapo matumizi yetu voltage ni ya chini. Kwa mfano, kabla ya matibabu ya chuma ni 60-70 ° C. Kufua ni 50 ° C na kadhalika. Kama tunaweza kuivunja kwa kiwango cha chini cha joto na kuzalisha nishati, kwa nini tusifanye hivyo? Hiyo ndiyo tumefanya katika Wheels India Padi yetu. Sisi kuacha juu joto thermal mtiririko mistari, na badala yake kukimbia chini joto mchakato kwa kutumia joto jua kwamba kuzalisha mahitaji ya joto la chini.
