Gas digesters with normal gas production have a high methane content and require sufficient air for combustion. Biogas digesters with just-injected or just-changed gas production are not normal. The methane content is low, and if there is too much air, it will go off and extinguish. Therefore, it is necessary to adjust the damper according to the specific situation. The flaps are two butterfly stainless steel pieces, divided into large fire dampers and small fire dampers. They are located at the front end of the inlet of the burner, and the lid closes the damper. When the cooker is in normal use, first adjust the large fire door and then adjust the small fire door. The normal flame is blue. A reddish flame proves that the methane content is low, and the gas is not pure; when the flame leaves the furnace, the amount of air entering the furnace is too large; the flames are connected into one piece with a damper that is too small; when the damper is too small, the flame is very high and looks very hot. This kind of flame heat value is not high. Generally, a piezoelectric ignition cooker can only use electronic ignition if it has a good temperament. If the gas is not pure, do not rush to use electronic ignition. The electronic ignition cooker is a high-efficiency and energy-saving biogas stove with a large pressure range, but the ideal pressure is 1.6 Kpa. If the pressure is too high, the biogas flow needs to be reduced by a pressure regulator switch.
AKD Wax
1. Introduction
This ADK wax is a very ideal neutral Paper Sizing Agent, it can be used as pulp sizing and surface sizing to make the paper have excellent water resistance. When using this ADK wax, it should be heated to melt, and then mixed with the starch emulsifying agent and protective agent, until the agent emulsify into stable latex

4. Application of Alkyl Ketene Dimer
As a kind of reactive neutral paper sizing agent, mainly used for copper base paper, copy paper, file paper, paper dictionary and quality writing paper paper in sizing. The pH value can reach about 8, which is called basic sizing, which is widely used at home and abroad. This product can also be used as surface sizing agent.
