Chemical, Physical and Thermal Properties of Methane - CH4. Phase diagram included. Thermophysical properties of methanol. Stable and efficient combustion requires correct mixture of fuels and oxygen. Properties like heat values, air/fuel ratios, flame speed, flame temperatures, ignition temperatures, flash points and flammability limits.

Volumetric Heating Values are based on standard temperatures and pressure of dry gas - 60 o F and 14.73 psi. Combustion heat values for gases like acetylene, blast furnace gas, ethane, biogas and more - Gross and Net values.

Note: Emission factors are per unit of heat content using higher heating values (HHV). If heat content is available from the fuel supplier, it is preferable to use that value. If not, default heat contents are provided.

甲烷（CH4）和一氧化碳（CO）的高位热值（Higher Heating Value, HHV）和低位热值（Lower Heating Value, LHV）通常在国家或国际标准中有规定。 这些值表示燃料完全燃烧时每单位质量或体积所能释放的能量，其中高位热值包括了水蒸气凝结时释放的潜热，而低位热值不包括 ...

燃烧热 （英语： Heat of combustion）（Δ c H 0）是指101kPa时，1莫耳纯物质完全燃烧生成稳定的氧化物时候放出的热量。 它一般用单位物质的量、单位质量或单位体积的燃料燃烧时放出的能量计量，当燃烧热以kJ/mol为单位计时又叫作 标准摩尔燃烧焓。 燃烧反应通常是 烃 类在氧气中燃烧生成二氧化碳、水并放热的反应。 燃烧热可以用弹式 量热计 测量，也可以直接查表获得反应物、产物的 标准摩尔生成焓 (Δ f H 0)再相减求得。 其中，燃烧热与 反应热 的关系为： 有时 燃料 …

Online calculator, figures and tables showing density and specific weight of methane, CH 4, at temperatures ranging from -160 to 725 °C (-260 to 1300 °F) at atmospheric and higher pressure - Imperial and SI Units.

This guide demonstrates how to use Cantera’s thermodynamic data to calculate the lower heating value (LHV) and higher heating value (HHV) of methane and other fuels. The complete reaction for heating methane is:

May 25, 2024 · Higher Heating Value (HHV): Also known as the gross calorific value, HHV of methane is about 55.5 MJ/kg (MegaJoules per kilogram). This value represents the total amount of heat released when methane is completely combusted and the water vapor in the exhaust is condensed, thus capturing its latent heat.

You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to calculate the mass or volume given a certain heating value. Choose whether you want to convert to heating value or to mass/volume, and then choose the fuel type.

Oct 2, 2024 · 对于甲烷，其高热值（HHV）约为55.5 MJ/kg，而低热值（LHV）则约为50.1 MJ/kg。 这些值表示在燃烧1公斤甲烷时，分别能释放55.5兆焦耳或50.1兆焦耳的能量。 热值计算公式
