New technical design auto project Clay brick Tunnel kiln
IBRICK Tunnel kiln is an advanced and automatic technology in brick making industry.
Tunnel kiln adopt large section with inner width of 4.6meter, it is designed as a flat ceiling structure with refractory bricks. Considering bricks can not have black center and patterns, the firing fuel source is major by inner-mixing-coal, outer-casting-coal as replenish, the heat should meet the firing technology requirement. This kiln is suitable for firing products with 1600-2600KJ/Kg.
Tunnel kiln has smoke-releasing system, recycling system, waste-heat recovery system, cooling system and pressure balancing system. This kiln has following features: large section, high yield, small section temperature difference, good heat preservation effect. Meanwhile, the kiln auto-control system is equipped to ensure the baking heat parameters are stable, so the firing quality is guaranteed.
A tunnel kiln is a type of continuous working kiln that is typically open on both ends and heated centrally. Building materials, such as bricks, may be passed through the device in an uninterrupted fashion, allowing large volumes to be processed without shutting off the kiln between batches.
Fuel
A number of different methods can be used to fired tunnel kiln. Typical burnt sources include coal, gas oil ,heavy oil ,natural gas...
Automatic Computer-controlled
Tunnel Kilns are computer-controlled, continuously operating car-bottom kilns. Computer technology allows kiln car movement through the kiln to be controlled for changes in firing curves and firing temperatures. Automatic controls can be programmed to make firing changes for differences in product size and color.
High capacity
Dried bricks via the hydraulic ferry pusher are sent to the trail car. Then, the workers push the drying car onto the trail car, then send to the Hoffman kiln / tunnel kiln for unloading, stacking and firing.
Ferry Pushers move the train of cars non-stop at a predetermined rate. This method is ideal for all ceramic industries requiring high volume production and/or a continuous production process.
Technical service:
We have professional ibrick technical team do the kiln construction, supervision, machinery installation, commissioning. it means we provide one-stop service and whole responsibility.
We have many success turnkey brick production line project in Bangladesh, Algeria,Russia,Uzbekistan,India ,Nepal,Africa, Saudi Arabia, Syria, Indonesia
If you want to set up a new brick plant or reforming the old brick factory, please find and tell us your request, we will provide professional technical design and supporting to you .
Tunnel kiln is the most popular kiln to use for building clay brick making process, It is easy to design for automatic production line comparing with traditional kilns, We can offer the best designs for customers, in order to reduce the cost and increase the production rate.
Our company not only provides customers with various brick machines, but also provides services like process design of clay brick, hoffman kiln design and construction, brick dryer design and construction. Undertake turn-key project and project contract.
Our engineers design and help customers build hoffman kiln and brick making factory.
Tunnel kiln
Fuel for firing: Coal, nature gas, oil
Firing temperature: Around 950 degree
Length of tunnel kiln: 144m for annual capacity 30million PCS bricks, (the dimension of kiln will be different according to different capacity)
The quantity of kiln cart in kiln: 32
The pass percentage: ≥ 95%
The advantages of the tunnel kiln:
1. Continuous work reduces the cycle period
High output
3. Performance of temperature keeping
4. Low fuel consumption
5. Saves the manpower
6. Environmental friendly.
7. Longer life.
We offered drawing layout and technicians to guide building the whole plant, including tunnel Kiln with tunnel dryer, or provide turnkey project. Building the whole plant, we will install machinery and conduct trial operation, after that we will train your local personnel how to operate the machines and how to maintain them daily. If you need more information, please send your detailed requirements to us.
------ Structure
Foundation: Tunnel kiln is with strip foundation. From bottom to up by order is lime soil, rubble, reinforced concrete girder (railway girder)/ board (under kiln wall)
Wall: Red brick is laid for the pre-heating zone and cooling zone where the temperature is below 200ºC. The rest is adopt combined wall. The fireclay bricks will be laid on the baking zone and inner wall of insulting zone. The clay insulting bricks will be used for laying the insulting area. Meanwhile, refractory fabric felt ( for the relative part of temperature curve above 600 Celsius) or rock wool felt will be used for stuffing and red bricks will be laid on the external wall.
Kiln roof structure: One kiln car space remained in low temperature zone on both sides, which adopt cast-in concrete top slab. For other position, clay material plate, hanger plate through davit hang under H type steel beam by cast product. Both sides firebrick wall support the main beam's weight. Refractory fibrofelt, rock wool felt, rock wool board are put on the refractory hander plate, which compose complex insulation layer. High temperature binder is being filled up to the gap between the boards, and is being painted on the upside of the insulating layer, thus to ensure the material's insulativity and structure's durability.
Coal casting hole: It is with function such as following, replenish heat, debugging, observation, replenish oxygen or cooling under negative pressure, releasing heat under positive pressure etc. This is widely used for tunnel kiln process with inner fuel technology, which can not be cut down or cancelled.
Sand seal: Sand seal slot is being put in the kiln cart skirt board, which insulate the high temperature from outside, thus to avoid cold air sucked into kiln under negative pressure which will lower the kiln temperature, and to avoid high temperature gas go to kiln cart underside under positive pressure which will destroy the kiln cart steel structure or deform the railway.
----- Afterheat system
Products direct heat and afterheat system are being put on top of the tunnel kiln, temperature curve in 450-200 ºC range. Extractive afterheat occupies 80% of the total required heat for drying, heat source clean and no pollution. Through heat exchanger, except whole factory workshop heating, the rest high temperature gas is being sent into drying chamber. Direct heat is being extracted quickly and effectively, this will shorten the kiln length so that to lower the kiln construction investment.
