What is silica level in boilers?
silica level changes according to boiler type sub or super critical boiler but its level should be less than 200ppm at rated condition
In a reaction If the energy of a product is less where does excess the energy go?
It is released as heat and/or light, the reaction is said to be exothermic.
What is natural draft in a boiler?
when the weight of warm air in the stack is less than the cool air around the stack , it causes an upward flow pulling air thru the furnace
Can the mass of the limiting reagent be higher than the mass of the excess reagent?
it may be , the limiting reactant is that which is totally consumed during the reaction but its amount must be less than required amount with respect to excess reactant for example, H2SO4 + 2NaOH = Na2SO4 + 2H2O in this reaction suppose acid is 95 g and base is 85 g but acid with higher amount is the limiting reactant and base is in excess. Essentially, it's possible whenever the molecular weight of the limiting reagent is higher than the molecular weights of the other reagents.
Are carbon atoms changed during burning?
Burning is a combustion reaction, which is a type of oxidation-reduction reaction. During combustion, carbon is oxidized. This means that it oxidation state becomes more positive, since it loses electrons during the reaction (it is bonded to the more electronegative oxygen after the reaction, whereas it was bonded to less electronegative hydrogen before the reaction).
What is silica level in boilers?
silica level changes according to boiler type sub or super critical boiler but its level should be less than 200ppm at rated condition
Where can one find spare boiler parts?
Spare boiler parts are best sourced from a reputable home heating specialist. Although much less expensive, boil parts made by amateurs and hobbyists are not safe.
Why did farmers waste truck loads of milk during the great depression?
Farmers wasted their milk so they could decrease inflation on the milk. Less milk + popular demand = more expensive milk
When does excess supply occur?
Excess supply occurs when, at a given time, the equilibrium price of the market is less than the price that the goods are supplied at.
Why India is not sufficient for food?
india is not sufficient with for food due to excess population and very less cultivating land to produce food for the excess population
Why boiler drum in cylindrical shape?
because in cylindrical shape stress concentration is less so it can withstand at high pressure also.
What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
During a drought is there less or more rainfall?
During a drought there is less rainfall.
Where can you go to from England with a flight time less than 3 hours?
spain, bulgaria, abiza. LOADS OF PLACES!
If load varies than efficency?
If loads varies then efficiency is less steeply than efficiency. This is taught in science.
Why lpf wattmeter used in no load?
Basically at noloads the current value is less so we use lpf at no loads
Is it possible to run a steam boiler very much lesser than design pressure for a long time?
Absolutely. Typical practice is to operate boilers at less than design pressure to reduce stress on the boiler parts. The boilers last longer than design, often.
