Description
Affiliated technical field
The utility model relates to a kind of roller kilns, is meant a kind of pulse control ratio burning wide roller kiln especially.
Background technology
Fired ceramic generally adopts roller kilns, tunnel cave, the Thermal Equipment of shuttle kiln three major types type, because pulse-combustion proportion control structure is at tunnel cave, application on the shuttle kiln, cause tunnel cave, shuttle kiln is at the width of kiln body, highly, the uniformity of temperature and the aspects such as stability of atmosphere are far ahead of roller kilns, tunnel cave can be accomplished 9.2 meters of inner widths, interior high 2.6 meters, upper and lower temperature difference, the left and right sides temperature difference all is no more than 10 degree, and shuttle kiln more can be accomplished 4.1 meters of inner widths, interior high 2.1 meters, upper and lower temperature difference, the left and right sides temperature difference all is no more than 5 degree, and atmosphere is controlled effectively, and energy consumption reduces a lot;
Pulse-combustion just looks like the same energy of periodically exporting of human heart, burner is periodically burning between big fire and little fire, heat is constantly output between height, thereby reaching temperature-averaging distributes and very economical fuel economy, the constantly pulse-combustion mutually in the height fire of pulse-combustion burner, promote thermal current convection current mutually in kiln, thereby reach the very little temperature difference, perfect condition is that the temperature difference is near zero, the temperature difference is also very little in actual use, convection current is strengthened in pulse-combustion exactly, can finish 5-20 time pulse-combustion within 1 minute, and the pulse period is more little, the thermal current convection current is strong more, the temperature difference is more little, and using pulse-combustion the most significant on kiln is exactly that energy consumption is low, have a narrow range of temperature, atmosphere is stable, thereby satisfies the requirement that wide section kiln is fired product;
Proportion control is exactly the ratio of fuel and combustion air in the control combustion process, thereby reach the purpose that cuts down the consumption of energy, optimal burning is that the ratio of fuel and needed air is 1: 1, temperature is the highest, energy consumption is minimum, ratio is exactly to reduce flame less than 1, and surpassing 1 is exactly oxidizing flame, uses reducing flame and oxidizing flame by the product decision of being fired, it is oxidizing flame that ceramic burns till major part, coefficient of excess air 1.05 the bests of gas in actual use, coefficient of excess air 1.1 the bests of light diesel fuel, heavy oil reaches 1.2, proportion control is exactly the coefficient of excess air in the control fuel combustion process, reach best fired state, the too much or not enough air burning of air, ignition temperature all reduces, energy consumption increases, have only the ratio of control air just can reach optimal burning till, energy consumption drops to minimum, and atmosphere is stable;
Existing roller kilns reach the limit of on the width of kiln owing to still adopt original control and combustion technology, once width is greater than after 2.5 meters, the temperature difference is too big in the kiln, aberration strengthens, and quality declines to a great extent, and therefore 2.5 meters width become the limit of a No overtaking of roller kilns; Pulse-combustion proportion control structure is as a kind of structure of high burning efficiency, at first invention is used on shuttle kiln, effect is very desirable, then on wide bore tunnel kiln, be extensive use of, result of use is equally very desirable, yet even adopted pulse-combustion proportion control structure, the energy consumption of shuttle kiln and tunnel cave is still quite serious, the energy consumption of shuttle kiln is 2 times of tunnel cave, about 4 times of roller kilns; The energy consumption of tunnel cave is also about 2 times of roller kilns; If can be to roller kilns with pulse-combustion proportion control structure applications, can cut down the consumption of energy effectively, reduce the temperature difference, roller way kiln just can be done wideer greatlyyer, single kiln output just can be bigger, and efficient also can significantly improve, thereby produce the huge social benefit, therefore how to provide a kind of roller kilns that use the impulse ratio burning structure, become a difficult problem of pendulum in face of people.
