Boiler installation of "blast doors," What is the role now on the market most of the combined 650 bhp boilers to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.
Fast one side condensing combined 650 bhp boiler steam condensate integrally advanced technology, with high efficiency, appearance, durable, cost savings, reduced noise, low nitrogen environmental advantages; self-developed by use of flue gas condenser waste heat boiler greatly increased thermal efficiency, while reducing emissions of harmful substances, can save a lot of fuel, compared with ordinary boilers, the average annual fuel cost savings of several million. Fast and well-equipped boiler unique cloud service 3.0 system, through remote monitoring of boiler operation, all-round ensure the safe operation of boiler.
Many of the coal ash will happen after combustion in the boiler, in order to safeguard the health needs of the environment will be transported to the ash professional processing slag field, however, the use of gas-fired boiler is gas, there will be no remaining after combustion ash, so do not need to process it, not only to avoid the formation of environmental pollution also decreased the labor intensity and the amount of urban ash storage and transportation companies.
Gas combined 650 bhp boiler safe handling as the country increasingly stringent emission standards for air pollution, the country has already started work boilers from coal to gas, out of heavily polluting coal-fired boilers, gas boilers using clean fuels. In this regard, Kono Tips boiler, gas boiler process, the need to pay attention to some safety issues: 1. burner to keep the working environment clean and dry, burner cleaning and maintenance once per shift to the control circuit must not get wet, affected by high temperature. 2. Check the electrical installations, mainly: whether the damaged wire, jacket damage, without loosening the screws, the contact is good, the motor is running any abnormal sound. 3. During normal operation, the burner portion close to thermodynamic device (such as a flange connection part) will be very hot, to avoid burns. Do not place near flammable materials, so as not to cause a fire. 4. combustor during startup, if the burner is locked repeated alarm reasons should be identified, and then identify failures and excluded press the reset button (pressing the reset button must not exceed 10 seconds), continue to start. 5. After the total gas pipeline experienced a temporary power failure solenoid valve (steel tile shed) to stop gas supply will automatically shut down until the first call burner electric alarm device to send, then a small hammer solenoid valve with total on hand to pull, you must first send electricity to manually open solenoid valve, solenoid valve will be closed and vice versa total. 6. fireman not mess-tune the burner, abnormal promptly notify management personnel, approved by management and then make adjustments. 7. In the long-term shutdown state, to do maintenance work on the boiler equipment, for each transmission parts to clean, lubricate.Free Chat
