Question

The heating load of a building at winter design conditions is XXXXXXXXXXBtu/hr (with pick-up allowance). From the performance specifications for commercial gas-fired hot water boilers provided in Table 6.2, select a boiler that can efficiently meet this load based on the

a. MBH output rating

b. I = B = R net rating

Answer: Given: The heating load of a building is 1510000 Btu/hr
To find: a boiler that can efficiently meet this load on the basis of its
a. MBH output rating
b. I = B = R net rating
Solution: To select the boiler we’ll use table 6.2 as shown below:
Given the heating load of a building or the input is 1510000 Btu/hr
Firstly, we convert it into MBH
As 1000 Btu/hr = 1 MBH
Or 1 Btu/hr = 1 MBH/1000 Btu/hr, 
Hence,

The heating load of a building at winter design conditions is XXXXXXXXXXBtu/hr (with pick-up allowance). From the performance specifications for commercial gas-fired hot water boilers provided in...
