Second, the fire-breathing form of choice From the Shanghai area, the fire road fire-breathing anti firewalls Spitfire Spitfire and shadow wall three forms. 1 . Road work fire flame furnace chamber is heated by the flame from the fire on both sides of the chamber bottom channel (Figure 2), the fire-breathing form suitable for the chamber width greater than or equal to 2. 5 m of fuel, coal drying sand furnace, since the fire road is long, high-temperature flame to be cooled down, when coupled with the upper hand amount is less pressure, it will form a reduction reaction conditions, the formation of CO, so that the heat efficiency.2 . Anti-anti-firewall firewall Spitfire Spitfire (Figure 3) are generally used for forging furnace, annealing furnace, the advantage is heating up fast, anti-fire stroke big, but there are shortcomings, the furnace temperature, heating uneven.3 . Shadow wall flame combustion chamber temperature flame through shadow wall of flame holes (Figure 4) to heat the workpiece, the advantages are: temperature more moderate, reasonable hot air convection; easy to adjust. Adjustable wall grate holes and a dispensing position to achieve the optimum distribution of high-temperature flame, and the furnace temperature is small, usually 5. About ℃, to ensure the quality of castings annealing, the structure is simple, small amount of stored heat. When the oven chamber width greater than 2. 5 m, it can burn from both sides.Based on the above analysis, I think of different uses of the furnace should adopt different forms Spitfire, for casting furnace may be anti-firewall flame, oven and timeliness of the annealing furnace can shadow wall Spitfire. Thus, 50 tons aging annealing furnace reconstruction select shadow wall Spitfire form.
Third, push coal arrangement 1 Vertical on both sides of the cloth dish of this arrangement either from the temperature distribution of hot air convection or from the point of view is reasonable, operation and processing coal is also convenient.Shanghai Compressor wide 60 tons annealing furnace on the use of this program, annealing reliable quality, the average temperature is less than 50 ℃. I plant 50 Tons of annealing furnace due to the restrictions of the original base position, only use the following layout scheme. 2 . Parallel to the sides parallel arrangement (FIG. 5) on both sides of the brie as good as reasonable the above scheme, but the actual use situation, the temperature not more than 50 ℃ annealing quality to meet the requirements of the workpiece.
IV. Determine the parameters of 1 . Grate width based on the amount of data I coal plant manual and Shanghai Metallurgical Design Institute provided, and with reference to the relevant technical information to determine the effective area F and grate grate width b respectively: F = B / 4 b F = 3 6 0/4 x 1 0 5 = 0. 8 6 (m's) where an amount of coal B, B = 3 60k g Kwong, combustion intensity West F a grate, stone F == 1 0 0 ~ 1 1 okg / m, fifteen. effective length b = F / L = 0. 8 6 VIII. 3 do 二 0. 6 3 (m) where the effective length L of a grate, 700 reciprocating push coal is 1. 3 9 m, width o. 7 m. Reciprocating push coal required number of units "is calculated using the formula: n = B / b F = 360/1 0 0 = 3 6, 4 (Taiwan) According to calculations, the choice of 4 700 to push coal summer. 2 . Exhaust system furnace volume V:.. By two B / by = 1 1 0/1 0 0 1 1 B a two coal-fired capacity (m ") wherein the amount of each coal-fired grate to take 110 k g / h, 2 O I 5 1 O 5 4 QOO 5 0 0 0 6 00 0 of 00 0 8 0 () J Coal heating Lian (l: c Sichuan / k child 6 theoretical air requirement b y a furnace heat intensity. Generally take l o o k g / two 3 • h.
ACRE Coking & Refractory Engineering Technology Co., Ltd. has developed a coking chamber height 6.25 m tamping coke oven's first 6.25 m tamping coke in March 2009 went into operation in Tangshan Jiahua Coal Chemical Co., At 6.25 m tamping coke oven machinery and equipment used SCP- machine (tamping, loading coal, coke pushing machine), the device is Germany KOCH company and Tianjin Xingang Shipbuilding Heavy Industry Co., Ltd. cooperation manufacture. With the smooth operation's first 6.25 m tamping coke oven, one after another manufacturers began to select the furnace, in order to meet market needs, Taiyuan Heavy Industry Co., Ltd. developed the 6.25 m SCP a machine.
