Large water tube boiler, FGR recycle flue gas and fresh air mixed with common configuration mixing bellows.According to the difference of placement position, it is divided into pre-premix and post-premix.Pre-mixing is the mixing bellows placed in the blower before, after the inclusion of reincarnated smoke and fresh air, in the air blower, was sent to the incinerator intervention incineration, in the mixed air in the air duct before the air blast configuration trap, crowd out condensate water, fan selection should also choose anti-erosion fan.After premix, after the mixing bellows are placed in the blower, the regenerated flue gas is sent to the mixing bellows after being regenerated. After mixing with the fresh air from the blower, it is sent to the incinerator for incineration.The commissioning condition of the blower is superior to the pre-premixed condition. However, a large amount of condensed water will occur in the air duct, so that a steam trap should be configured at the low point of the mixing bellows and the smoke air duct.
The light oil and heavy oil pumps supplied by Europa are equipped with filters, pumps and heaters (heavy oil), filters and oil pumps together or double-way one-stand-one-use plan.The acceptance of a two-way system ensures that the system does not need to be obstructed by normal inspection or discovery of obstructions.Heavy oil can be heated by electricity, heat conduction oil and steam ring to reach the viscosity required for atomization.
Oubao supplies safe type of light oil and heavy oil matching valve set, fuel required for incinerator quick active cut off the valve, atomizing ring quick active cut off the valve, related to the oil gun blowing quick active cut off the valve, pressure master, pressure gauge and temperature gauge (heavy oil only), modular plan makes placement quick and light.
From the perspective of heat exchange calculation, it is necessary to increase the heat exchange surface, improve the heat exchange compliance of the heating surface, improve the heat exchange temperature difference of the cooling source at a lower temperature, and reduce the influence of erosion on the heat exchange compliance.As gas steam kettle host start burning furnace volume and content low nitrogen flame size request, the second host of convection heating surface is a main export to low smoke temperature, average in 150 ~ 250 ° C, in order to survive the smoke temperature is too high growth together with the difficulty of flue heat preservation plan, smoke temperature is too low will cause wall condensation in furnace convection heating surface lead to erosion, therefore, proper heating furnace domestic demand plan, the physical dimension more representative chamber size.To increase the heat exchange surface, it is important to think about increasing the heat exchange area of the building at the end of the boiler, which is more beneficial to the rapidly lowering smoke exhaust temperature.Second, the lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, it can accept the construction of corrosion-resistant materials and improve its service life.The new layout of efficient heat exchange must adopt the modes of staggered tube arrangement, efficient heat exchange finned tube and plate heat exchanger, increase the smoke disturbance and battle surface, reduce the smoke stratified heat resistance, advance medium and smoke heat exchange compliance.
Generally speaking, the building belongs to the hardware of energy-saving base, but the double important is the human element, a good management team, may exercise good people to control every joint, in the operation of every energy-saving factor, continue to summarize the progress of the management and control of the team, this is the software.And an energy-saving management operation in the face of the company, not only face up to the construction of hardware and software in the face of more construction, they are supporting control high-grade attached to the machine control system, good appearance, have been supervised exercise the global flow very get really running data, attached to the machine system in a happy place, in the promotion of the artificial intelligence technology, will the parties face into the dispute machine in the French concession mind and exercise of new means of science and technology take the initiative to control each node, cut salaries turnovers, missed, accurate control the economic system running in high efficiency and energy saving status forever, with is,A comprehensive, reasonable and excellent computer control system is a very good object for human management.
Energy saving is a general project, each node should be controlled, the enterprise needs to invest a large number of manpower and material resources, the enterprise will continue to improve the degree of management, but also continue to harvest energy saving and consumption reduction efficiency, create better economic benefits.
