The present invention has a reasonable structure, compact, low steel consumption, performance, weight, size and structure of the boiler with the same capacity has significantly improved compared to the advantage of domestic products. Boiler work process: a substantially uniform coal particles by an automatic stoker coal thrown into the hopper, preheated before entering the arch in the case of rotating chain grate. Were burned in the incineration zone, fell into the slag pool. The high temperature flue gas produced by combustion of the furnace arch port into the furnace from a lower portion of the rear flue two wings, the wings and then heat the flue, through the forward flow before the packets enter the convection heat transfer tube bundle, then the tail tube boiler and dust entering the economizer section, and discharged to the atmosphere through a chimney to the induced fan. Boiler feed water is supplied by a boiler feed pump, demineralized water supplied by the economizer, and then enters the drum, and then enter the downcomer around header. Endothermic steam is generated by vaporizing water wall on both sides, into the steam within the steam separator drum, after separation, the main steam valve into the process heat required.
Fuel oil combustion process differs from the process industry Industrial Combustion fuel oil-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.
Effect of boiler fine coal combustion boiler operating principle is to use thermal energy or heat in industrial post fuel released by combustion is transferred to the water in the container, the temperature or pressure of the water reaches a certain desired steam heating equipment. Many people will feel that coal-fired boiler more detailed the better, but is it really? From a combustion point of view, the finer coal particles more easily form a good mixing with the air, the more complete the combustion. But the coal particles too small, for boilers, milling power consumption will be greatly increased. Industrial boiler, the coal into the furnace too small, there will be the following questions: 1, coal leakage losses, etc. from grate gap increased. 2, boiler grate to be at full speed, power consumption increases. 3, fly ash, fuel loss increases. 4, a coal burning ember i.e., unstable combustion, furnace volume heat load difficult to sustain stable. So the boiler when using fine particles of coal, coal is subject to how much water, raw coal water, play groups and then into the furnace. If the burning coal of 8 to 12h before the water, so that the penetration of moisture into the interior of the coal particles is better. Water vapor produced is moistened triatomic gases, flue gas can strengthen radiation, facilitate ignition, exhaust and reduce heat loss
