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.

Problematic fired boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.
