What is the best biogas stove?
Suitable primary air parametersGeneral household biogas stove is an atmospheric burner, required combustion air supply is composed of two parts, one part is from the ejector suction inlet, in advance of biogas and biogas combustion mixture, called an air. The other part of the gas is burned by the side of the atmosphere around the flame, known as the two air.The ratio of primary air to theoretical air is called the primary air parameter, which is represented by A. A= primary air volume / theoretical air volumeThe primary air coefficient is an important index to measure the performance of biogas stove. It depends on the mode of combustion. General atmospheric biogas stove, a value from 0.85 to 0.90.
High thermal efficiencyThermal efficiency refers to the ratio of the heat absorbed by the heated object and the heat released by the biogas stove. The thermal efficiency is related to the combustion and heat transfer process of the whole methane, which is a comprehensive coefficient affected by many factors. In order to improve the thermal efficiency, it is necessary to make full combustion of methane, and make full use of heat. General requirements for thermal efficiency shall not be less than 55%.
First, high quality cooking standards(1) with suitable heat loadThe utility model relates to a heat load of a biogas stove, which means that when the utility model is used, the heat generated by the combustion of methane can be released for one hour. Units usually kcal / h. The heat load is too large, the pot is too late to absorb, the fire ran out of the pot, the heat loss is large, the efficiency is low, waste methane, this time can shorten the cooking time, but the time is not significantly reduced. The utility model has the advantages that the heat load is too small, the cooking time is prolonged, and the cooking heat requirement can not be satisfied. So the heat load is too large, too small are not suitable. General household biogas stove heat load of 2400Kcal/ H (kcal / h).
Biogas stove is a kind of tool used for cooking, and the advantages and disadvantages of biogas stove directly affect the user's use effect. To make full combustion of methane, to meet the needs of living energy, we must use high-quality cooking stoves, and learn the right way to use.
