How to judge whether the steam boiler is energy-saving
For the majority of users and friends, it is very important to purchase a boiler that can save energy and reduce emissions when purchasing a boiler, which is related to the cost and cost performance of the subsequent use of the boiler. So how do you see whether the boiler is an energy-saving type when purchasing a boiler? Nobeth has summarized the following aspects to help you make better boiler selection.
1. When designing the boiler, the reasonable selection of equipment should be carried out first. In order to ensure that the safety and energy saving of industrial boilers meet the requirements of users, it is necessary to choose the appropriate boiler according to the local conditions, and design the boiler type according to the scientific and reasonable selection principle.
2. When selecting the type of boiler, the fuel of the boiler should also be correctly selected. The type of fuel should be reasonably selected according to the type, industry, and installation area of the boiler. Reasonable coal blending, so that the moisture, ash, volatile matter, particle size, etc. of the coal meet the requirements of imported boiler combustion equipment. At the same time, encourage the use of new energy sources such as straw briquettes as alternative fuels or blended fuels.
3. When selecting fans and water pumps, it is necessary to choose new high-efficiency and energy-saving products, and not to choose outdated products; match the water pumps, fans and motors according to the operating conditions of the boiler to avoid the phenomenon of “big horses and small carts”. Auxiliary machines with low efficiency and high energy consumption should be modified or replaced with high-efficiency and energy-saving products.
4. Boilers generally have the highest efficiency when the rated load is 80% to 90%. As the load decreases, the efficiency will also decrease. Generally, it is sufficient to select a boiler whose capacity is 10% larger than the actual steam consumption. If the selected parameters are not correct, according to the series standards, a boiler with a higher parameter can be selected. The selection of boiler auxiliary equipment should also refer to the above principles to avoid “big horses and small carts”.
5. To reasonably determine the number of boilers, in principle, the normal inspection and shutdown of the boilers should be considered.
