kalkulasi perhitungan pipa steam boiler
Procedure boiler boost? Boiler boosting steps are as follows: 1 when the pressure was raised to 0.05; when 0.1MPa, rinsing drum water level gauge. 2. When the pressure was raised to 0.15; 0.2MPa time, closing the drum door air, dehumidifiers hydrophobic door header. 3. When the pressure was raised to 0.25; 0.3MPa when, sequentially lower header sewage water wall door, note drum water level, the boiler feed water should be closed drum, economizer inlet to the recirculation door. 4. When the pressure was raised to 0.3MPa, the notification instrument (h) flushing pipe tables, the contact main steam turbine door open doors steam heating pipe, when the pressure was raised to 0.6; when 0.7MPa, the main valve fully open close the bypass valve. 5. When the pressure was raised to 1MPa, thermal notification into water gauge. 6. When the pressure rose when 2MPa, steady pressure to the boiler conduct a comprehensive inspection found irregularities should be stopped boost, until the fault is cleared, continue to step-up, pressure increased to 2.4MPa, sewage regularly turn. 7. When the pressure rose to 3; when 3.4MPa, rinse Water Level Indicator, notification chemical laboratory quality soft drinks, and equipment to conduct a comprehensive inspection. Boiler and steam conditions
From the operation state of the boiler, circulating fluidized bed boiler of biomass advantage was significantly higher than biomass boiler chain grate boiler, circulating fluidized bed straw combustion technology is good for the characteristics of circulating fluidized bed combustion in nature,professional study pointed out, the boiler in solving the problem of low melting, straw burning in the slag, alkali metal deposition, high and low temperature corrosion and the agglomeration problem than the grate combustion has obvious advantages in the straw burning, can play a unique role.
In the boiler heat losses, heat losses of water vapor carried by 55% to 75% of the heat losses, if the flue gas temperature down to flue gas condensation temperature, by recycling the latent heat of water vapor, can be very effective reduce heat loss and improve the thermal efficiency of the boiler. Condensing boiler flue gas temperature can be dropped to below 40 ℃ ~ 50 ℃, not only the latent heat of vaporization of water vapor can be recovered, but also removing harmful substances in the flue gas; thermal efficiency also increases as the amount of condensation of water vapor increases.
Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast boiler R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
