Experiment and analysis of temperature distribution of straw double-grate briquette boiler furnace-tank

Under four different working conditions (the smallest air valve αPY = 1.6, the smaller air valve αpy = 2.2, the larger air valve αpy = 3.2 and the largest air valve αpy = 4.4), the double fire grate boiler designed by the author was tested. The corresponding result is that the temperature distribution does not show similar in height direction, depth direction and width direction. Secure, stable and economical operation of the boiler can be realized on the better work state (between state 2 and state 3). It could be an important type of straw briquette boiler. It lays the foundation for optimization design of burning equipment and running adjustment.
