Lpg Fired Heavy Oil Steam Boiler


Lpg Fired Heavy Oil Steam Boiler

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

Multi-fuel lpg fired steam boiler protection water protection Fuel steam boiler: boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. A steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. 2, the safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection: imported burner having a flame protection device, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power failure protection: Under the emergency power supply is interrupted, the boiler shutdown immediately self-locking, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

Some knowledge boiler Introduction: boiler is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Today introduced are several little knowledge about the boiler. 1, a way to improve the efficiency of the boiler A which:? ⑴ low heat losses: prevent heating surface fouling and coking, the rational use of the burner, controls the blower inlet air temperature, water temperature of attention to the impact, into the furnace to avoid excessive wind note impact milling system operation; ⑵ mechanical incomplete combustion to reduce heat loss: rationally adjust the fineness of pulverized coal, the excess air ratio control of appropriate, attention combustion adjustment; ⑶ quality assurance fired boilers; ⑷ reduce soda losses: guaranteed boiler quality water supply, installation and maintenance to improve the quality of the steam separator means, to maintain the operation of the boiler load, the water level, steam pressure and other parameters of stability, so that the boiler water separation apparatus operating under normal conditions; ⑸ index management adhere to the small boiler. ? What are the reasons boiler fire answer: ⑴ low boiler load, low temperature furnace, combustion temperature, combustion oil investment is not timely; ⑵ poor coal quality, low volatile matter, ash is too large; ⑶ air volume to adjust properly, once too high wind speed, wind powder imbalance, the excess air ratio is too large; ⑷ excessive negative pressure maintaining furnace; ⑸ bunker powder level is too low or fallen powder to the powder to make the powder unevenness; ⑸ large depression coke furnace, disturbances in the furnace is too large; ⑹ ash, coke playing time is too long, especially large caused by cold air leakage into the furnace temperature drops to a low load; ⑺ blast furnace tube, a large number of soft drinks into the furnace; ⑻ fire protection action; ⑼ device malfunction, such as sending, fan, tripping of mill, Auxiliary disappeared.

Oil-fired boiler combustion control and automation and whether the fuel tank on the role of specific types of boiler, this article will be introduced below, for this kind of boiler oil-fired boiler, but for now, this kind of boiler is widely application, is a common and popular types of boilers, so based on these two points, it should be taken seriously and work to learn the product, good to have a good use of effects through proper use. Notes 1. What are oil-fired boilers? This oil-fired boiler A boiler, through which the oil is atomized fuel oil burners, and then mixed with air, in suspension a combustion apparatus for combustion in the furnace. Larger capacity fuel boilers, mostly use heavy, but the larger the viscosity of heavy oil must be preheated before combustion; if the capacity is small, is the use of light oil, no need for preheat. In addition, oil-fired boilers for industrial use, mostly fueled with the use of light diesel oil. 2. whether the oil-fired boiler combustion and control system can be automated? The issue from a professional point of view, the answer is you can, that is, oil-fired boiler burning automation and control systems can be used. In addition, this kind of boiler fuel needs to be injected into the boiler furnace combustion chamber and the use of fire, there is no need to use grates facilities. Fuel oil-fired boiler does not produce ash after combustion, therefore, do not need to slagging facilities. 3. Does the oil-fired boiler have different classification criteria? It corresponds to the specific types of what? This kind of boiler oil-fired boiler, which is a different classification criteria, and correspond to different species at different classification criteria. If the fuel according to the type can be divided into two heavy gas oil boilers and boiler, light oil and kerosene are those diesel, heavy oil refers to crude oil after extraction remaining heavy gasoline or diesel oil. If use according to points, can be divided into a fuel oil-fired boiler water boilers, hot water boiler fuel, heating fuel boiler, oil bath boilers and lpg fired steam boiler fuel these. 4. whether the oil-fired boiler can be automatic oil burner? Why have their fuel tanks? On oil-fired boilers, can be automated using the oil burner, the ignition from the normal combustion, the air supply from the oil supply to the flame detector, and so can be automatic protection automatically, without manual operation. And this kind of boiler installed on the tank, one can play a role in filtering sediment, and second, to solve this problem come from oil-absorbing far away.
