industrial heavy oil fired water boiler manufacturing
Modulation (the capacity to vary the boiler output) is a key concern for biomass steam boilers. Generally biomass boilers will only modulate to 40% of their capacity. A typical oil burner will modulate to 20%, and with the installation of multiple burners, oil boilers can modulate to very low output. Biomass boilers respond much less rapidly to variations in load. From start-up they can take several hours to get up to the required temperature and pressure. Steam is much more difficult to store than hot water. The boiler will have some in-built thermal storage and the use of steam accumulators provides some flexibility, but the key barrier at many sites is that a biomass steam boiler should be designed for a consistently required base-load.
Application of heating Boiler Control systemThe heating boiler is equipped with a special microcomputer controller for hot industrial fired water boiler manufacturing, large screen full Chinese liquid crystal screen, with super bright backlight, no matter day or night, the operation status of the boiler is clearly visible. Complete display: circulating pump working condition, burner working condition, furnace water temperature, water level, current time, alarm record, etc., boiler operation condition is all available; Easy to set: after the boiler starts, the operator can enter the standby state (setting), enter the running state (start), exit the running state (stop), and set the running parameters at will when the boiler is on standby. Full-featured: you can set the current time at any time , alarm temperature, water temperature upper limit temperature, water temperature lower limit temperature, circulating pump opening temperature, circulating pump closing temperature, boiler switching time (can be divided into 4 time periods) and other operating parameters. Usually the operator just press; start the start key, press; Stop the key stop can, very simple use of the original imported burner, fully automatic programmed control, fan automatic blowing, electronic automatic ignition, automatic combustion of oil and gas, air and oil (gas) automatic proportional adjustment, atomization effect is good, combustion is full, Energy-saving and environmental protection, with extinguishing protection device to ensure the safety of combustion. Under normal conditions, the burner output automatically adjusts the length of the combustion flame with the boiler temperature When the outlet temperature of the boiler reaches the set value, the burner automatically stops burning, and when the temperature is below the set value, the burner starts to work automatically. When the fuel and intake air are abnormal, the fault light is on, the program control device will stop outputting the fuel immediately, and the burner will stop automatically.
Boiler ignition How hard? Preparatory work must be done in place! We see, out of sight, the boiler provides a steady stream of power, supporting all aspects of our daily life and industrial production needs, making great contributions to urban development and social progress of civilization. When you buy the right to their own businesses boiler equipment, how to properly operate the boiler operation becomes very important. In order to ensure the normal operation of the boiler, before ignition must be strictly checked and fully prepared; to do the following seven steps before you can begin to start the ignition. A, check and adjust the water level in the boiler water level adjusting on the display of digital boiler water gauge, when the boiler water level below the normal level required, when the water level above the normal water level will have to open the drain valve timing drainage, the water level reaches a predetermined. The water level should not exceed the normal water line when the boiler for the first time (cold oven) Sheung Shui. This is because the boiler ignition, industrial fired water boiler manufacturing thermal expansion is likely to exceed safe water line. Once this happens, the water level should be adjusted by sewage. If the water table level and table column is connected, to check whether the valve opening meter column connected tube. If the water table glass contamination, poor resolution, and must be cleaned or replaced with new equipment. Second, the former boiler blowdown test run, the test should be done on the sewage discharge valve, the valve is fully closed after confirming good, be careful not to have leakage. Third, check the pressure gauge to check the position of the pressure gauge; boiler no pressure gauge pointer should be limited stop limiting, the staple of the staple, the pointer value from zero gauge should not exceed the predetermined allowable error. When the gauge does not meet the requirements should be promptly replaced. Note that the header gauge cock in the open position. Fourth, check the water supply system of water storage tank to check the adequacy of whether the water supply piping and valves open. Manual and automatic water supply for the test, to confirm its good performance, the correct action. Fifth, check the furnace flue damper open ventilation will begin ventilation, have induced draft fan should start induced draft fan for ventilation. If the natural ventilation flue long and winding, ventilation time is generally less than 10 minutes; the wind if mechanical ventilation, generally less than 5 minutes. Six, ventilation equipment inspection and inspection of all fuel grate transmission section condition, to remain intact, normal rotation job. Reserves the liquid fuel tank should be checked, the gas fuel check gas reserves, and while confirming the oil pressure is normal. Fuel lines, filters, fuel pumps, the valve opening and closing the pipeline should be checked to ensure that no exception. Start oil heater, oil maintaining an appropriate temperature. Check the opening and closing of the control valve to meet the requirements. Confirm alarms work properly. Check flame monitor light-receiving surface and protects the lens is clear and transparent. Restrict the chain system is normal. Seven check automatic control device close the power switch, the power indicator confirmed by the control panel is turned on. Check the medium (air) and the fuel line for each valve opening and closing state of the pipeline, which confirmed that no leakage, no abnormal. Check the water level detection device, the specified maximum and minimum water level at the limit, the ability to correctly stop the pump and start pumping. Check the opening and closing of the control valve to meet the requirements. Low water level alarm can confirm correct operation. Check flame monitor light-receiving surface and protects the lens is clear and transparent
