How much gas a 30-ton boiler uses in an hour directly determines the daily operating cost of the boiler, which is the main operating cost. Many users don't know how much gas a 30-ton boiler uses in an hour, which is more energy-saving.
How much gas does a 30-ton boiler use in an hour?
The gas consumption of SZS30-ton boiler in one hour is about 2037 nm/h, which is generally superior to that of similar gas boilers. According to the calculation formula of gas consumption of gas-fired boilers, h...
With the increasing awareness of energy conservation and environmental protection, gas-fired boilers have become the necessary heating equipment for most enterprises. So the question is, what kind of gas does the gas boiler burn?
1. natural gas
Because of its low sulfur content and high calorific value, natural gas is a clean energy source. When choosing what gas to burn in gas-fired boilers, users generally choose it. Natural gas is a general name of hydrocarbon-based mixed gas existing in un...
The reduction of nitrogen oxides in gas-fired boilers is mainly achieved by burners and increasing the furnace size of boilers. In order to help enterprises save costs and reduce nitrogen oxides in gas-fired boilers, low-nitrogen transformation can be realized by configuring appropriate low-nitrogen burners and staged combustion technology plus the flue gas internal circulation technology, and the emission can be controlled to be less than 30 mg/m3.
When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure equipment, in accordance with local regulations.
The fuel of a gas-fired boiler is gas such as natural gas, city gas, biogas and liquefied gas, etc. What kind of fuel the boiler burns is decided by an equipment called a burner. The boiler equipped with a gas-fired burner is called a gas-fired boiler. There are three methods of gas-fired boiler combustion as per technical characteristics of how the gas and air mix.
1. Diffusion combustion:
Gas and air mutually diffuse at the gas nozzle and are burning. The advantages are burning stably and with simple burner structure. However, the heated area is easy to be carbonized due to long flame, which is easy to produce incomplete combustion.
2. Premixed combustion:
A part of air and gas are premixed before combustion (coefficient of primary air surplus is between 0.2-0.8), and then being burned. The advantages are clear combustion flame, enhanced combustion, and high thermal efficiency.
The combustion air will be heated to the flame temperature. This heating cost money. If you have some waste heat to be used for preheating the combustion air it will pay.
The selection of a burner of the gas-fired thermal oil heater should be determined according to the boiler proper structure and fuel characteristics and in combination with the actual conditions and requirements. In addition, this kind of boiler can adopt a waste heat recovery device to improve thermal efficiency and reduce heat energy loss.
Fuel-to-steam efficiency is a measure of the overall efficiency of the boiler. It accounts for the effectiveness of the heat exchanger as well as the radiation and convection losses. It is an indication of the true boiler efficiency and should be the efficiency used in economic evaluations. As prescribed by the ASME Power Test Code, PTC 4.1, the fuel-to-steam efficiency of a boiler can be determined by two methods: the InputOutput Method and the Heat Loss Method.
