The invention provides a combustion furnace. The combustion furnace is used for coal combustion, generated smoke is changed into sludge fertilizer, clean gas is discharged to the environment, the fog hazard degree is lowered, and high chimneys do not need to be constructed. Smoke and gas which are generated after coal combustion are subjected to two times of shower water spraying and one time of chemical agent processing under the effect of closed system terminal electric fan pumping and is discharged into the atmosphere after being purified, and sludge formed after the smoke is subjected to shower water spraying and precipitates can be used as the fertilizer. The combustion furnace can be used for coal combustion for heating of north residents, coal combustion in plants in all places, coal combustion in brickyards in all places, and the like.

A solution TOC concentration in-situ initial measurement and pre-judgment method adopts a three-electrode system of a voltammetry method, takes a graphite electrode as a working electrode, takes a mercurous sulfate electrode as a reference electrode, takes a platinum electrode as a counter electrode, adopts a current-time mode of an electrochemical workstation to measure diffusion current, and establishes a linear relation between the current and the TOC concentration; according to the diffusion current of a to-be-detected solution, the initial measurement value of the TOC concentration is calculated from the established standard curve, and accordingly whether the to-be-detected solution needs to be diluted or not and the specific dilution multiple are judged. The method is suitable for initial measurement and pre-judgment of the TOC concentration in water bodies such as soil solutions, natural water and domestic sewage. The method is convenient and rapid, can effectively solve the tedious time-consuming and labor-consuming problems of blind on-machine measurement, multi-dilution on-machine measurement and the like when a TOC analyzer is used for measuring a high-content TOC sample, greatly reduces the loss of an oxidizing agent and a catalyst in the TOC analyzer adopting a wet oxidation or high-temperature catalytic combustion oxidation method, protects the column efficiency, and prolongs the service lives of the oxidant and the catalyst.
