5 ton steam coal fired boiler

5 ton steam coal fired boiler

Boiler structure have? The whole structure, including 5 ton steam coal fired boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.

For more than two decades, it has been the focus on clean 5 ton steam coal fired boilers, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.

Advancing the ignition point of coal, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the 5 ton steam coal fired boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.

Fuel oil combustion process differs from the process industry Industrial Combustion fuel oil-fired 5 ton steam coal fired boilers for industrial oil fired boilers and industrial boilers, having a certain temperature and pressure injected into the furnace through the nozzle is atomized into fine droplets, and then absorbs heat in the furnace, vertical oil-fired boiler, surface gradually vaporized into oil, mixed with intake air in the furnace, form a combustible mixture. The combustible mixture continues endotherm temperature reached ignition ignition combustion. Fuel amount, air amount and the amount of the composite has a one to one relationship of steam, it is necessary according to the load amount of steam required to control the amount of fuel and air supply, but also by the wind furnace pressure control apparatus. Different oil-fired boiler with a different point of industrial coal-fired boilers point of industrial boiler fuel industry and industrial coal-fired boilers. PM2.5 pollution damage to the environment led some coal-fired boilers industrial boilers is facing new boiler renovation or change of situation, which makes oil-fired boiler to become the darling of the market. Oil-fired boiler with a coal-fired boiler in comparison with structurally quite different purposes, as follows: (1) injecting fuel into the boiler furnace through the burner, combustion chamber without using fire grate facilities; (2) Since the oil, gas did not produce combustion ash, it is no oil or gas boiler slag and slag outlet device; (3) injecting a gas or oil furnace materialized, if mixed with air or flame within a certain range, is easy to form an explosive gas, Thus fuel (gas) required automated combustion boiler system, comprising a flame monitoring, flame protection, explosion-proof safety; (4) Since the oil, gas calorific value is much larger than the calorific value of coal, so the thermal strength than fired furnace high multi-furnace, so relatively small and the capacity of the boiler with coal-fired boilers, compact, small footprint; combustion process (5) fuel (gas) is suspended in a boiler furnace, the furnace is provided so its before and after the arch, the furnace structure is very simple. Meter manufacturing, Supervision, Inspection and the main characteristics of biomass fuel boilers [] protection devices and control systems introduced a biomass fired boiler biomass fuel boilers are in strict accordance with "Steam Boiler Safety Supervision", JB / T10094-2002 "general industrial boilers technical conditions ", JB / T1619-2002" shell boiler body manufacturing technology, "execution, ensure long-term security and stability of the boilers. Body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, stretched stretch, combustion heat load is low, less NOx emissions of harmful substances. Waveform furnace and threaded pipe structure that improves the strength, but also to meet the needs of each portion of the thermal expansion. Master butt welds are connected, and by X-ray and ultrasonic nondestructive testing, to ensure the welding quality to meet national requirements. Boiler water volume and large air space, adaptable load capacity. Design reasonable pot, with water vapor to ensure that less than 4%, to meet user requirements for higher quality steam. Using the new insulation materials, light weight, low heat loss, good insulation properties. Water level alarm stainless steel rods as electrodes, an insulating material as polytetrafluoroethylene. Inserted from above, linked to pollution easy, reliable, and long service life. Before and after the smoke box is hinged, can easily open, repair and maintenance quick and easy maintenance. Adjusting the oxygen content (optional): The system can successfully monitor the oxygen content in the flue gas, and transfer the data to the real-time control systems, intelligent analysis by a computer, the automatic adjustment device stoichiometric combustion, it is in real-time good working shape, combustion efficiency is greatly improved, which can significantly reduce fuel consumption. Biomass fuel boiler operation timing of the protection device, the operation of the control system by the timer, the system automatically enters the work or off duty. The control system may be provided multiple sets of the timing period within 24 hours. Any period of time in a group of a plurality of sets of timing of the current time period, the system enters the working state. Work within the timing period, the status screen is displayed automatically. In the period of time in commuting to work outside the state. Each group comprises a turn-on time period (hour, minutes) and a closing time (hours, minutes) may be set or modified when the three control period, divided by the setting operation and the current time. The user can set different time different temperature ranges.
