Gas Steam Boiler Guide: Gas Consumption Of 4 Ton Gas Steam Boiler
Gas consumption of a 4-ton gas steam boiler, whose fuel consumption is one of the concerns of many customers. Then, how much is the fuel consumption of an ordinary natural gas steam boiler? How to calculate the gas consumption in a steam boiler? What is the gas consumption of a 4-ton gas steam boiler? And is directly related to the input cost. I will tell you about it in this paper.
Determine the boiler gas consumption
The gas consumption of gas-fired steam boilers is closely related to the stoker’s stoker experience. Not only the gas consumption but also the safe operation of the boiler is very important. Therefore, the relevant state departments stipulate that the stoker must have a stoker certificate. Which is a manifestation of being responsible to the user unit, the stoker, and the society.
In simple terms, the determining factor of the gas consumption of the boiler is the heating area of the boiler. The calorific value of the fuel, the purity of the fuel, the heating area of the boiler convection, the radiation heating area of the boiler, and the stoker skill of the stoker.
The fuel consumption of natural gas steam boilers is one of the concerns of many customers. Then, how much is the fuel consumption of an ordinary natural gas steam boiler? We can calculate gas consumption in accordance with the following parameters: The heating value of natural gas is 35.53MJ / m³, which is calculated by the standard calorific value 0.845m³ / m³.
The best-rated 4-ton steam boiler manufactured by Fangkuai is a high-efficiency industrial steam boiler adopting double buttons quick-loading structure that can reduce overall dimensions and weight as well as simplify installation work. Compared with the traditional single-button quick-loading structure, its overall dimensions decreased by 10% and its weight decreased by 15%. The specially designed combustion chamber has double buttons for quick loading, which improves the thermal efficiency of the furnace and increases the power output.
Determine the output of the boiler.
how to calculate boiler horsepower
The output of a ton of boilers is 600,000 kcal, and so on, the output of a 4-ton gas boiler is 2.4 million kcal.
The output of a boiler is calculated by multiplying its thermal efficiency by its heat input rate, then adding this value to its latent heat content (the amount of energy required to vaporize water at 100°C). Depending on which type of fuel you’re using, this value will be different. For instance, if your plant uses natural gas as its primary fuel source, then your thermal efficiency will be between 35% and 40%. To determine your plant’s average thermal efficiency, take an average over several months and use it in future calculations.
The calorific value of general natural gas is 8400 kcal per cubic meter, and the calorific value of diesel is 10240 kcal per kilogram.
From the observed rise in temperature of the water and the container, the calorific value of the fuel can be determined by equating the heat given out by the fuel to the heat taken by the water and the container. In order to know the heat taken by the container, the water equivalent of the container should be known.
The calorific value of a fuel is the amount of heat energy that it has per unit weight. This is important to know because you need to know how much heat your boiler can generate from a certain quantity of fuel, and you also need to know whether or not your boiler will require extra fuel for generating steam.
For example, oil has about 50% higher calorific value than coal does Therefore, if you were using oil instead of coal as your boiler fuel and using exactly the same amount of each type (that is, 100 kg), then half as much oil would be needed compared with coal.
The best-rated 4-ton steam boiler manufactured by Fangkuai is a high-efficiency industrial steam boiler adopting double buttons quick-loading structure that can reduce overall dimensions and weight as well as simplify installation work. The 4-ton gas-fired steam boiler consumes 4-ton gas per hour, so you need to prepare the same amount of natural gas for operation.
If the boiler is equipped with advanced technology, it will be easy to use and maintain it.
Looking for boilers with sophisticated manufacturing, and great quality?
In general, the fuel consumption of a 4-ton gas steam boiler is about 101 cubic meters. When it comes to the application industry of 4-ton steam boilers, many customers pay more attention to their own operating costs. According to the above introduction.
