  • Water flowing through a gas-fired boiler at the rate

    Question: Water flowing through a gas-fired boiler at the rate of 2 kg.s-1 is heated from 30 C to 85 C. That heat is obtained by cooling hot gas from 1,000 C to 350 C. Given the values below for specific heat (Cp) of the gas and the water, calculate the mass flow rate of gas in kg.s-1. Cp,gas = 1.10 kJ.kg-1.K-1 Cp,water = 4.18 kJ.kg-1.K-1Learn More

  • firing rate of he boiler? — Heating Help: The Wall

    Hot water systems are controlled by both a thermostat and an aquastat -- the thermostat tells the system that heat is needed (it does that for steam, too, of course!). The aquastat -- in more efficient systems, in conjunction with an outdoor reset -- tells the boiler that the circulating water isn't hot enough, and turns on the boiler.Learn More
