Hoffman Kiln
Due to continuous operation and large production capacity of hoffman kiln, and the fuel required during the baked progress mostly come from cooling zone which has been preheated hot air. And the combustion products - flue gas by preheating with time, can be used fully to preheat brick, and the exhaust gas temperature is only about 100 ~ 120 ℃, thus to the rational use of fuel combustion heat, so that the fuel consumption per unit of product is much lower than intermittent kilns.
Coal consumption of hoffman kiln firing every ten thousand standard brick (size 240 x115 × 53 mm) includes its inner coal consumption of fuel and foreign investment, and the amount of coal is generally 0.8 ~ 1.0t of coal (its heat QPH = 2.93 * 1000kj / kg).
The necessary supporting mechanical and steel consumption equipment in hoffman kiln are low investment, it is easy to be launched. The vast majority of many local township brick enterprises will choose this type of kiln. Compared with the kiln, using hoffman kiln firing products, in line with the requirements of energy conservation, but also adapt to the early rural township enterprises financial and technical management level.
