As is known to all, the coal fired boiler is a horizontal three-way water-fire tube hybrid boiler with a bunch of threaded smoke pipes arranged inside the boiler barrel. Coal fired industrial boilers left and right sides of the furnace are equipped with light tube water cooling walls. It adopts chain grate, equipped with blower and induced draft fan for mechanical ventilation. DZL series boiler combustion equipment for chain grate. The water cooling walls on the left and right sides of the furnace are the radiation heating surface, the two wings of the furnace are the convection heating surface, the threaded smoke pipe is arranged in the pot barrel, the front and rear arch are made of the new process of heat resistant concrete casting and ramming as a whole, and the outer side of the main boiler body is the three-dimensional protective plate shell.
This series of coal-fired boilers adopt quick installation and can be operated by installing valves, instruments, drums, induced draft fans, smoke air pipes, dust removers and water and electricity roads when they arrive at the site of use. Easy installation and movement can save a lot of capital investment. The whole boiler combustion process for fuel from coal bucket on the front of the fire grate, with grate operation, after preheating dry distillation, fire, coal combustion, state slag fall into slag bucket, row from time to time by the slag machine, smoke can form between before and after the arch eddy mixing with air, and heating before arch, improve fire condition, the upper arch export smokestack convection water wall tube bundle into two wings, through the smoke box into the threaded pipe, before after economizer, dust catcher, by induced draft fan to chimneys.
DZL series coal fired boilers adopt new scientific research results, such as: arch tube plate, threaded smoke pipe, etc., to solve the pot shell boiler tube plate cracks, pot lower drum bulge, water wall burst pipe, low thermal efficiency, insufficient output, poor adaptability to coal and other problems. The rising pipe row is arranged in the lower part of the boiler barrel of coal-fired boiler, which eliminates the dead water area at the bottom of the boiler barrel. Coal fired industrial boilers sludge is not easy to deposit, the pot can get good cooling in the high temperature area, and prevent the lower drum of boiler shell. The high efficiency heat transfer pipe is adopted to strengthen the heat transfer effect, achieve the characteristics of boiler heating up and fast output, and improve the thermal efficiency of the boiler.
Industrial coal fired boilers are compact in structure, smaller in size than similar boilers, saving investment in boiler house infrastructure. Stable operation, convenient adjustment, full output, overload capacity wall. This series of boilers adopt threaded smoke pipe to enhance heat transfer, improve heat transfer coefficient and thermal efficiency, because the smoke in the pipe has the disturbance function, the smoke pipe is not easy to accumulate ash, plays the role of self-cleaning. The high efficiency and energy saving furnace arch, which is made of heat resistant concrete, is used in the furnace chamber to improve the condition of coal fire, and the independent air chamber is used to distribute the air reasonably, which makes the furnace chamber form an air dynamic field favorable to combustion, thus expanding the adaptability of coal varieties.
Coal fired industrial boilers of furnace arch and the smoke window have a certain effect of dust removal. The original dust concentration of the boiler is controlled below the standard to ensure that the soot emission of the boiler can meet the target of environmental protection regulation.
