1. Gas-fired hot water boiler selection
1. Calculation formula for heating heat consumption:
Heating standard: 100w/m2
Heat consumption formula = 100×total area×860/1000
2, the calculation formula of heat consumption required for 1t water to heat up 40℃:
Example: For example, if the user needs 5t of water per hour, the heating value of the boiler power required is
3. Calculation formulas applicable to various heat loss (such as Oike, etc.):
Q=mc△t=? (This question mark represents the weight of water in tons) X1000LX3℃=?
Example: A 10t large pond is calculated at a temperature drop of 3℃ per hour:
10T×1000L×3=30000kcal/h. The resulting heat loss per hour is 30,000 kcal, and the heat loss will be added back later.
To sum up, a 1 ton gas-fired hot water boiler can provide a heating area of 6000-8000 square meters and can be equipped with 60 shower heads.
2. Operating Costs of Gas-fired Hot Water Boiler
Among the operating costs of boilers, fuel costs account for the largest proportion, fuel costs = fuel consumption * unit price
Fuel consumption of gas-fired hot water boiler = boiler heating capacity ÷ thermal efficiency ÷ fuel calorific value
Take a 1 ton gas-fired hot water boiler as an example, the fuel consumption = 60 million Kcal÷92%÷8400Kcal/m³=78m³
1 ton gas-fired hot water boiler fuel cost = 78m³*3 yuan/m³=234 yuan (the unit price of natural gas is calculated at 3 yuan/m³)
Note: The above calculation is the fuel cost when the boiler is operating at full load. In most cases, the boiler is not operating at full load, and the actual operating cost of the boiler is less than this value. If you need to know the actual cost, please consult our company.
