pilot oil pump oil fired steam boiler

Boiler installation of "blast doors," What is the role now on the market most of the 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 pilot pump fired 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.

Strengthen the inspection of law enforcement inspection, severely crack down on open burning of straw behavior. Increase efforts to promote comprehensive utilization technology of straw, conditional county incentives to take subsidies. Focus on sugarcane crop leaf prohibiting the work, in accordance with the principle of territorial management, the development of sugar cane leaves prohibiting management program, to strengthen the unified management, unified utilization, unified treatment and disposal. Municipal Agricultural Bureau, the Municipal Office of the sugar industry to strengthen guidance and support for the comprehensive development of the use of sugar cane leaves, the full implementation of mechanized harvesting of sugarcane, sugar cane fields and comprehensive utilization of straw has broken.

2, urban dust comprehensive management of special operations. The urban dust control content into the focus of supervision and improve the system of dust control mechanisms, the establishment of the construction site with information technology platform construction, water conservancy projects, the implementation of dynamic site inventory management. Supervise the implementation of the site around the site enclosure, stockpiling cover, wet earth excavation work, the main road hardening, cleaning out the vehicle, sediment transport vehicles sealed "six percent", temporarily unable to start construction land should be covered. The construction site dust pollution prevention and control into the "civilized construction" category management, dust control costs are included in the project cost; according to the law will not be in place of harmful dust management information into the construction market credit management system, in serious cases, be included in the construction market players " blacklist". Rinse vigorously promote road sweeping mechanized operations, improve road mechanized cleaning of urban built-up area. Sediment transport, coal, ore, gravel and other transportation vehicle is not confined to do, strictly punished according to law.

3, industrial enterprises air pollution comprehensive management of special operations. According to Beihai City "scattered pollution" inventory accounting, to further improve that standard and rectification requirements, classification of promoting the "messy dirty" business regulation, focusing on remediation of the city and the surrounding "messy dirty" business. Strengthen the coal-fired boilers (including biomass boilers) and brick, ceramics and other industries industrial furnaces supervision, strengthen law enforcement. Encryption of iron and steel, building materials, nonferrous metals, thermal power, cement, brick, calcium carbonate and other business materials (waste) storage, handling, crushing, transportation and other aspects of the inspection frequency of inspections, strict implementation of consecutive daily penalties, limited production shutdown and other means strictly according to law penalties for environmental violations. Focus sessions focused their attention on the process of pollution, thermal power, steel, cement, bricks, ceramics, wood processing, sugar high emission enterprises, especially in built-up urban area of ​​business, and strictly control the total amount of air pollutant emissions.

Multiple protection devices take you through the oil pilot pump fired steam boiler oil steam boiler water level protection, 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. 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. 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, having imported burner flame protection means, 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 protection case, the boiler shutdown immediately burst self-locking power interruption, 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.

Gas-fired pilot pump fired steam boiler safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.
