Heinz has claimed that it steam peals its tomatoes rather
than using the chemical lye method. Let's calculate the
energy required to produce 50,000 lb/h of saturated
steam for the process.
The heat required to bring 70 °F water up to a boiling
point of 212 °F is given by
Q = m(SpHt)AT
BTU
BTU
Where Q is the heat input in , h is the mass flow rate in .Spit is the specific heat in
and AT is the temperature dif ference in °F
Once the water is heated to the bõiling point of 212°F (at sea level) it must be
vaporized to steam. The equation is
O = Am
BTU
Where Q is the heat Input in m is the mass flow rate in and
Ib
BTU
A is the heat of vaporization in h
If the specific heat of water is 1.001 BTU/lbm and the heat of vaporization is 970.1
BTU/lbm, calculate the following
1. Calculate the heaf input (BTU/h) required to heat the water from 70 °F to the
boiling point of 212 °F.
2. Calculate the heat input (BTU/h) required to turn the water into steam.
3. What is the total heat input required to heat the water and turn it into steam?
4. What percent of the total heat input is required to heat the water?
