The problem with this approach is that it is costly and the failure rate of the pump is very high in the environment of high temperature and high solids, often causing failure to work no longer and thus affecting efficiency. In addition, in some boilers with large negative pressure, the sampling requires a large pump power to suck out the gas, and the cost is high, the efficiency is low and the life cycle is short.
Therefore, developing a thermal conduction gas sampling device with long service life, high compliance with product requirements and capability of meeting the requirement of accurate measurement environment is a technical problem which needs to be solved by those skilled in the art.
