Fumes from indoor cooking fires kill more than 2 million children a year in the developing world. MIT engineer Amy Smith details an exciting but simple solution: a tool for turning farm waste into clean-burning charcoal.

in 2008, together w/ my japanese friend mr junji takano, we developed an improved cooking stove 2help mitigate d black carbon emitted fr kitchen households utilizing charcoal or fuelwood. click on d link below 2see d pdf file

boiler efficiency & accidents

i’ve been doin research on boiler efficiency since this is one of d major areas where industrial companies can save a lot of money while minimizing their organization’s global warming potential. bad emissions is a sign of money being burnt….w/ dcost of fossil fuel continuously being volatile, making a boiler work efficiently should be d standard….fuel efficiency is not only bout money savings but also bout safety….an inefficient boiler means trouble….big trouble…it’s like dealing w/ a pressure cooker in d kitchen, it’s very dangerous when u don’t deal w/it properly.

at d start of this holly week, a heat exchanger tank of a boiler system exploded in a styrofoam factory in bulacan province. according 2d news, der wer almost a dozen pple killed in d accident.

many companies are converting their boilers 2utilize biomass just like this styrofoam factory, i.e. dey’r using rice husks as fuel 4d boiler. biomass boiler owners should be particularly carefull bout d fireside since soot accumulation is inevitable….soot in d fireside of a firetube boiler means less heat transfer so more fuel is needed 2burn 2heat d same amount f water. accordingly: ‘soot has five times the insulating value of asbestos. allowing it to accumulate in boiler firetubes wastes fuel-a 3/16″ accumulation in the firetubes will waste more than 20% of the boilers’ fuel.’

in d waterside, water scale, lime & rust accumulate n have a significant impact on heat transfer….more scales means more fuel needed…

therefore, bad boiler maintenance means bad air emissions, inefficient heat transfer, more fuel being burnt…and most of all….it can be an accident waiting 2happen….

when companies loose 10 million pesos (not including d cost of lost lives) like this styrofoam factory….dey will no longer think bout d cost-benefit-analysis of preventive maintenance….an efficient boiler is not only bad for d company’s bottomline in d short-term (due 2expenses 2b incurred) but also good 4d environment as well as d safety & health of d workers in d long-run….

if d styrofoam company can prove dat dey have a working boiler efficiency programĀ  (bep)….i can only agree dat wat happened is really an accident…

if companies can calculate how much savings is d 20% of deir million peso fuel expenses & d cost savings in preventing an accident….it will den be a no-brainer 2implement a bep…..
