SZS 2 ton h water tube oil and gas fired boiler

The Fangkuai Group's unique full-operating szs 2 ton h water tube oil and fired boiler operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.

6 tons gas steam szs 2 ton h water tube oil and fired boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

Industrial szs 2 ton h water tube oil and fired boiler energy-saving technological transformation of existing problems in industrial boiler energy-saving technological transformation of Question 1, the lack of innovation, application of energy-saving boiler mature, molding technology and equipment, such as: increased flue gas heat recovery unit, blowers inverter , condensate recovery and other conventional energy-saving measures is essentially a general condition; and the need for structural changes in energy-saving measures, such as fractional bed combustion of coal and boiler furnace arch transformation techniques, etc., are rare; as transformation project new principle, a new device, oxyfuel technology, high temperature air combustion technology, spray pulverized coal combustion technology (+ supernatant layer combustion boiler combustion mode), condensing heat recovery technology, new energy technologies dust ash and water treatment equipment, is very few. In general, innovation is not enough, the technical content needs to be improved. 2, part of the boiler is not fully considered in the transformation process, but simply changing the burner, the combustion gas flow distribution and does not match the corresponding surface of the heating boiler, the boiler furnace wall insulation and sealing transformation. There is poor combustion boiler, insufficient output, higher exhaust temperature problem, can not achieve the purpose of energy saving. 3, the waste heat boiler using high temperature organic heat required for thermal processes, a boiler generally at 200 ℃ 300 ℃, the exhaust gas temperature of the boiler is usually too high, excessive. In order to meet requirements of energy saving, companies often mounted in the boiler backpass evaporator or a hot water tank, flue gas waste heat recovery, reducing the exhaust temperature. But most of the heat generated in the production process does not require little energy. 4, statistical analysis of experimental data shows that there are many problems inefficiencies run natural gas boiler. The main concern of automatic combustion control, early production debugging is not in place, and so on. Gas boiler gas and incomplete combustion abnormal increase in heat loss caused by high temperature exhaust gas is the direct cause of poor operating efficiency. However, the use of clean energy natural gas boiler, generally higher thermal efficiency, energy saving difficult. Corporate restructuring investment funds enthusiasm is not high.

You have to know the energy consumption of szs 2 ton h water tube oil and fired boiler problems (control measures exhaust gas temperature of the boiler) 1, operational measures (1) unit load changes, to adjust air flow and pulverizing system operation mode, keeping the excess air ratio most suitable furnace. (2) time to adjust the bottom seal tank inlet valve, suitable to ensure the seal tank water level. (3) changes in coal quality, timely adjustment of combustion, complete combustion and ensure proper furnace flame center. (4) heating surface periodic soot blowing and slag, maintaining heating surface clean. (5) maintaining a suitable gas velocity, the heated area ash reduced tail. (6) Check the class auxiliary burner throttle opening, to ensure there is sufficient oxygen in the combustion. (7) raise the water temperature. 2, boiler routine maintenance and testing (1) combustion optimization and adjustment tests, to determine the economic coal fineness different coal. (2) periodic testing coal fineness, abnormal timely adjustment process. (3) regular air preheater leakage test, and remove air preheater leakage. (4) Always check the furnace to see the fire hole, furnace wall, bottom seal, identify problems and timely closure, reducing boiler leakage. (5) Strengthen routine maintenance soot blowers to closely monitor motor current soot blowers, for soot blowers and often stuck in the barrel bending furnace and other defects timely treatment to ensure soot blowers investment rate above 95%. 3, repair, downtime (1) Check the burner damage, to replace or repair damaged nozzles, the nozzle and the bluff body. (2) heating surface, the flue fouling, slagging cleaning up. (3) adjusting the fuel to determine the secondary air and the opening degree position of the damper flap. (4) Health Check flue gas damper, the damper position adjusting checked. (5) roof sealing, see the fire hole, Manhole, bottom seal tank leakage inspection governance. (6) replacing air preheater wave plate, rinsing, the check processing sector plate, curved plate is deformed, and bearing wear off defects, defect inspection process automatic adjustment mechanism sealing gap. (7) Pulverizing System: Mill off the door, the hot air and the cool air shutter opening degree adjustment. Roller cover and bowl mill liner replacement, the spring biasing force and gap adjustment. Import a fan baffle opening adjustment. (8) the flue expansion joint leakage defect inspection process. (9) soot blowers and related equipment check process. 4, transformation (1) Burner deformation, wear process, replacement, and a bluff body concentrator ceramic sheet, and silicon carbide wear measures. (2) the heated area ash slagging comprehensive inspection process. (3) waterwall, economizer, reheater, superheater tube cutting test monitor segments corrosion and scaling inside the case. (4) boiler, air preheater Leakage leak plugging governance. (5) on the "four leak" taken by plugging repair. (6) backpass wear parts wear welding process and do. (7) heating surface (economizer, superheater, reheater) for transformation, reduce exhaust gas temperature. (8) to do a good job adjusting the air according to test results dynamic field. (9) boiler, the flue joints and other advanced seal plastic material, to reduce leakage.
