15M2 Frit Furnace
1．1-General Description:
15m2燃气熔块炉炉型选择蓄热式马蹄焰池炉，为了节能，炉体采用复合全保温技术，减少炉体散热。为了提高蓄热室换热效果，同时避免粉尘堵塞格孔，格子体采用西门子上下不交错形式，为了降低消耗，保证生产稳定，质量可靠，整个生产过程从加料到出料、从燃烧到换向均采用自动、手动二项控制系统：手动控制操作简单、方便；自控系统控制精度高、运行可靠、稳定。二者切换方便。为了减少粉尘对环境污染，加料采用推臂加料机密封加料。
Regenerative horseshoe flame tank furnace is used for 15m2 gas energy saving frit furnace. To save energy, full compound insulation technology is applied to the furnace body to reduce heat radiation. SIMENS deinterlace pattern is applied to the grid to improve heat transfer effect as well as to avoid dust blocking holes. Auto and manual control systems, with easy switch with each other, are applied to complete production from feeding to discharging and from combustion to commutation, to reduce consumption and make production stable and quality reliable. Manual operation is simple and convenient while auto precise, reliable and stable. Feeder with tappet arm enables feeding in a closure to reduce dust pollution to environment.

Description of Frit furnace design/窑炉主要部位设计说明：

1、熔化池/ Melting pool：
窑炉面积15㎡，燃料为天然气，火焰燃烧相比重油火焰要短，刚性要弱，因此窑炉长宽比相对取小些，即5400/2800=1.93。
Area of 15 square meters of the furnace, fuel is natural gas, flame burning heavy oil flame compared to a short, rigid to be weak, kiln aspect ratios relative to take smaller, that is, 5400/2800=1.93.

2、池深确定/Chi Shen identified:
每天出料24吨/日，出料率1.6吨/米2。为了保证产品熔制质量，增大存料量对产品质量有利，因此池深选择800mm，为了节约投资，减少下次窑炉维修成本，池墙砖设上下二层，上层选用WS-33-AZS，下层选用PT-33-AZS（主要部位选用WS-41-AZS）。
Daily discharge 24 tons/day, the feed rate of 1.6 t/m 2. In order to guarantee the quality of products for melting, increase the amount of stock is good for product quality, so pool deep 800mm, in order to save investment, reduce the next kiln maintenance costs, the pool wall located up and down the second floor, the upper selection WS-33-AZS, the lower selection PT-33-AZS (main part of selection of WS-41-AZS).

3、火焰空间确定/Flame space：
为使火焰燃烧完全，保证炉膛内压力微正压，减少火焰对胸墙和炉碹冲刷，相对增大火焰空间比较有利，因此胸墙高度选择1000mm。胸墙外架150mm，采取独立支撑结构，胸墙和大炉碹采用烧结锆莫来石砖，可以保证使用寿命。
To make the flame entirely, guaranteed in the furnace pressure micro-pressure, reduce chest wall of flame and furnace arch in erosion, relatively more favorable increases space, chest wall height 1000mm. Chest wall shelf 150mm, independent support structures, chest wall and large furnace arch using zirconium mullet sintered brick, can guarantee the service life.

4、加料口确定/Feeding holes：
为了加快粉料熔化速度，采用预熔池加料口，形状为梯形，内口放大，加料口设一只，加料机选择推臂式加料机，加料速度由变频器调介，达到均衡密封加料。
In order to speed up the powder melting velocity, feeding hole using pre-pool, shape of a trapezoid, zoom, a feeding hole only, feeding machine select the push arm type feeding machine, feeding speed by inverter, balanced seal feeding.

5、出料系统设计/Output system Design：
出料系统传统采用挡料砖较普通,但使用寿命较短,为了延长使用寿命,出料系统设计采用流液洞形式。
Material system of traditional retaining bricks compared with ordinary, but shorter service life, in order to extend the life of discharging system design uses fluid forms.

6、小炉设计/Small furnace design：
为了保证火焰燃烧覆盖面宽，小炉宽度设计800mm，小炉面积占熔化池面积2.4%左右，每个小炉口设二只燃气喷枪，小炉下倾角选择23度。既保证火焰覆盖面又保证火焰强度。
In order to ensure the flame coverage width, width of furnace design 800mm, size of small furnaces melting pool an area around 2.4%, each small mouth is located the second gas gun only, select the 23 degree angle in small furnaces. Keep the flame coverage guaranteeing flame intensity.

7、蓄热室设计/Heat-reserve chamber design：
为了保证换热效果，格子体高度为40层，格子体选择西门子式上下不交错，避免粉尘堵塞格孔。
In order to ensure the effect of heat, grid height is 40-storey, Checker Choose Siemens not staggered up and down, to prevent dust plug hole.

8、其它系统设计/Others：
a、为了延长窑炉使用寿命，对池壁料液面附近和流液洞部位采用冷却风强制降温，尤其到窑炉后期效果明显。
In order to extend the life kiln, on the wall near the material surface and throat parts cool cooling air force, especially to the kiln late effect.

b、为了稳定生产，保证产品质量，对燃烧和换向采用自动控制，控制精度高、运行可靠。另外再设一套手动控制系统，操作简单。二者切换比较方便。
In order to stabilize the production to ensure product quality, combustion and directional control, high precision, reliable operation. Another set of a manual control system, operation is simple. Both switches easier.

c、为了节能，窑炉采用覆合全保温技术。
Energy-saving, furnace with covered-in-full-insulation technology.
