Lime kiln technical characteristics: (1) the combustion air is divided into primary and secondary air. Primary combustion air directly involved in the double-beam price of gas-burning kiln, secondary air for the cooling air. Primary and secondary air are supplied by a single fan. The design of the secondary air temperature can rise up to 600 ℃ gas-burning kiln as combustion air, in order to save fuel provide favorable conditions. (2) the use of special combustion system to rotary kiln heating, in addition to using pulverized coal as fuel outside the low calorific value gas can also be used alone (eg, producer gas, calcium carbide exhaust, semi-coke gas) as fuel firing can also use a variety of fuels At the same time supply use. The calcination temperature can be adjusted by adjusting the air and gas flow. (3) measures to improve environmental protection. Calcination exhaust using pulse jet bag filter dust, to meet the national emission standards. In the vertical blanking point cooler it is also used baghouse dust. (4) high level of automation. Calcined conditioning system equipment manufacturing operations, control and alarm using PLC (programmable logic controller) in the main control room centralized control of gas-burning kiln process, and a screen display of the control points and the necessary interlock monitoring, operating parameters used in the production process for automatic recording, and can be printed at any time. Analysis and handling common problems and faults: size too large: The rate of limestone and limestone particle size depends on the temperature of the surface in contact with lime. And at a certain temperature, the speed depends on limestone calcination of limestone particle size. Liaoduo bigger, slower firing speed. This is due to the thermal conductivity of less than lime lime burning proceeds, with increasing thickness of the layer of lime, heat it harder to enter the stones inside, its firing speed is getting slower and slower. Therefore, there is often a large piece of limestone sandwich, raw burnt lime first is the reason. Ordinary shaft kiln size should be controlled at 40 ~ 80mm for the good gas-burning kiln furnaces, kilns large capacity can be raised to 50 ~ 150mm, in order to save costs but also specialized in the use of limestone and small stone company in recent years, pulverized lime kiln specially designed gravel lime burning small size also good. Analysis and handling common problems and faults: a small proportion of the fuel or the calorific value of the fuel is low. Co-firing kiln technology performance and kiln fuel ratio, generally requires calorific value 5500 kcal. Size to have a certain control. Pulverized coal to be appropriate to add water.
