Gas hot water boiler is a kind of hot water boiler, gas fired hot water boiler with gas (such as natural gas, liquefied petroleum gas, city gas, biogas, etc.) as the fuel, through the burner to water heating, heating and providing hot water for living and bathing, boiler intelligent degree, fast heating, low noise, no dust, is a very suitable for China’s national conditions of the economic hot boiler varieties. Gas hot water boilers are widely used in hotels, schools, hotels, communities and other enterprises and institutions for heating, bathing and domestic hot water.
To know “how to calculate the thermal power of gas hot water boiler”, we must first solve a problem, what is the thermal power of gas hot water boiler? In China, the thermal power (symbolized by Q, the unit is megawatt (MW)) is used to indicate the rated heat supply of gas fired hot water boilers, the rated heat supply of gas hot water boilers refers to: the effective heat supply of hot water output per hour of the boilers in long-term continuous operation under the premise of ensuring safety.
Gas hot water boiler thermal power commonly used capacity: 0.7, 1.4, 2.8, 4.2, 7, 10.5, 14, 29, 46, 58, 70, 116MW So, how to calculate the thermal power of gas hot water boiler?
- 10,000,000 calories = 10,000,000 kilocalories (Kcal) = 10,000,000 calories (cal) = 4,185,8518.2 joules (j).
- 10,000 dcal Ì 11.6 kW (Kw) Example: 24 kW (Kw) boiler is approximately equal to 20,000 dcal boiler.
The formula for calculating the heat consumption required for 1t of water to warm up to 40℃: 1T×1000L×40℃=40,000kcal
Example: for example, the user needs 5t of water per hour, then the required thermal power of gas diesel hot water boiler heat value is 5tX40000Kcal = 200000Kcal. - Let’s take a look at the relationship between the thermal power of gas hot water boilers and the amount of heat supplied.
The formula for calculating the size of the heat (provided or lost): Q = cm △t, where c = specific heat capacity of the medium (if the medium is water, then c = 4200K/kg), m = medium mass, △t = medium temperature difference (exothermic heat absorption are temperature differences).
Example: How much heat is needed to burn 1 ton of hot water from 0℃ to 40℃ in one hour?
Q=cm△t=4200*1000*40=168000J (joules) ≈ 40000cal (calories)
Equivalent to a ton of water temperature rise one degree need heat 1000 calories, such as the user needs 5t of 40 ℃ water per hour, then the required gas hot water pot care power calorific value is 5tX40000Kcal = 200000Kcal.
