摘要： PURPOSE:To obtain a combustibility measuring apparatus and a combustion controller which achieve a measuring of combustibility handily and immediately for a fuel changing rapidly with unevenness of components, for example, city garbage to control combustion in an incinerator properly. CONSTITUTION:A sensor 13 having a heating body 1 is inserted into a fuel 12 to burn a part of the fuel and a combustion gas generated is sucked up with a gas analyzer 17 to analyze water, CO2, CO, hydrocarbon and other components while a heating value and ignitability of the fuel are measured from the composition of a produced gas. Based on the combustibility, an amount of combustion air to be sent to the main body 26 of an incinerator is controlled with valves 30 and 31. This enables the measurement of the combustibility handily and immediately by lower labor force for city garbage or the like difficult in estimating the combustibility when the amount of the sample is small. Proper control of combustion is possible by controlling burning conditions based on the combustibility thus obtained.

摘要： PURPOSE:To always maintain a stable combustion by quantitatively monitoring a scattered state of char continuously during operation and controlling combustion based on the result. CONSTITUTION:Black liquor is jetted from a burner 1 to a furnace 2, dried and thermally decomposed into char, which is dropped on the bottom of the furnace to form a char bed 3. The char bed 3 is produced by supplying about half of the total air amount from a primary air hole 4 and the greater part of the residual air from a secondary air hole 5. Char formed at the bottom of the furnace is made into scattered char 7, collides against a superheater pipe group 8 set at the top of the furnace and attached and piled on the pipe group. In a recovery boiler, a multiple point-thermometer 10 is arranged at the level part of a nose part 9, the temperature of a combustion gas at this level is measured to obtain a temperature distribution and the combustion state of black liquid can be monitored and controlled based on the temperature distribution.

摘要： PURPOSE:To burn a black liquor always at the most appropriate condition and reduce greatly the quantity of dispersed dusts by providing means to estimate the density of black liquor, means to calculate the liquid flow rate at a black liquor nozzle, means to calculate the heated temperature of the black liquor, and means to measure the viscosity. CONSTITUTION:The black liquor in a mixing tank 1 is supplied to a black liquor burner nozzle 3 that is installed on the wall face of the furnace 17 of a black liquor recovery boiler by means of a black liquor pump and jetted out into the furnace 17. The black liquor is heated to a specified temperature by a black liquor heater 2. For each kind of black liquor an estimated value 9 of the black liquor density is obtained by a black liquor specific gravity detection device 7, and based on this estimated value the black liquor viscosity setting 12 is made, and based on the set viscosity a most suitable grain diameter 11 is set. The viscosity required for obtaining this most suitable grain diameter is derived from the flow rate 10 given by the flow rate 8 of the black liquor and detected specific gravity 7, and the diameter of the nozzle used for atomizing the black liquor.

摘要： PURPOSE:To reduce clinker trouble, corrosion at high temp. as well as at low temp. due to P compd. and to permit stable continuous incineration of sludge by performing incineration after mixing a Ca compd. with sludge contg. P. CONSTITUTION:In a process for incinerating P-contg. waste water sludge by a fluidized bed furnace, etc. the sludge is mixed with a Ca compd. (e.g. lime stone) prior to incineration. As the result, clinker trouble and corrosion of the incineration furnace and cyclone, etc. are prevented, and stable continuous operation is permitted. Accordingly, installation for energy recovering such as air preheater, etc. has become possible, and reduction of energy consumption is realized. Furthermore, since acidic waste gas is removed simultaneously, installation of desulfurization apparatus is unnecessary. Therefore, the apparatus can be made compact easily.

摘要： PURPOSE:To obtain an adsorbent adsorbing mercury traces contained in a waste gas and waste water by providing the condition that sulphuric acid or sulfur oxide and vapor are adsorbed to an activated carbon. CONSTITUTION:After a waste gas produced in a combustion furnace 1 is desulfurized by an SO2 adsorption tower 2 via a flue 7 of the waste gas, said gas is discharged from a stack 5 via a flue 8 of the desulfurized gas to the atmosphere. The adsorbent adsorbed SO2 is conveyed to an SO2 desulfurized tower 3 through a conveying path 9 of the used adsorbent and is heated to produce concd. gaseous SO2 and is regenerated. The regenerated adsorbent is returned from the tower 3 to the tower 2 and is reutilized to desulfurize the waste gas, but the adsorbent subjected to abrasion and pulverization is drawn out on the way, and the pulverized carbon is used as an adsorbent of mercury.

摘要： PURPOSE:To lessen the consumption of adsorbent used due to oxidation as much as possible as well as miniaturize a cooler by cooling the adsorbent after being heated and regenerated by bringing it into contact with a low-temperature inert medium. CONSTITUTION:Waste gas from a boiler 6 is introduced into an adsorber 10, where SOx present in the waste gas is adsorbed and removed by an adsorbent from a carbonizer 24 and the waste gas so treated is released from a line 12. The SOx- adsorbed adsorbent is sent to a desorption apparatus 14 provided with a heating tube 61 for regeneration by heating. The high-temperature adsorbent so regenerated is brought into contact with an inert substance, e.g., sand, under enclosed condition in a cooler 70 for cooling, separated from the inert substance in a separator 73, and then again returned through a line 71 to the adsorber 10. The high-temperature inert substance is cooled in a heat exchanger 80, and then again returned through a line 71 to the cooler 70. SOx generated in the desorption apparatus 14 is sent through a line 38 to a sulfur recovery process.

摘要： PURPOSE:To reduce a mechanical damage of an adsorbent by a method wherein desulfurization is conducted in a condition in which an adsorbent is placed on a belt-type plate moving at right angle to the direction of gas flow. CONSTITUTION:Protruded sections 3 are provided at both sides of duct walls at right angle to the direction of waste gas flow. In the sections 3, pulleys 4 are installed and an endless belt-type metal net is placed on the pulleys. An adsorbent A consisting of semicoke is charged from the inlet 6 onto the metal net 5 so that it adosorbs SOx from waste gas while the net 5 moves in the duct as the drive pulleys 4 rotate. The waste gas 2, after desulfurized by the adsorbent A, passes through the gas passage holes formed in the metal net 5 and flows down in the duct. The adsorbent used is taken out of the outlet 7. Free adjustment of contact time between the waste gas and the adsorbent A is available by controlling the speed of the drive pulleys 4.
