What are the precautions in the selection and purchase of industrial aerated autoclaved concrete cost comparisons

Nowadays, the market share of industrial boiler is getting higher and higher. Washing and ironing, packaging machinery, biochemical industry and food industry will purchase it as a complete set of necessary equipment. The industrial boiler uses high quality stainless steel as the main material and imports high temperature magnesium oxide powder as the sealing material, so its temperature resistance is very strong. But when choosing and purchasing this kind of boiler, should pay more attention, through the omni-directional judgment to choose and purchase the high cost-effective boiler. So what are the precautions in the selection and purchase of industrial boilers?

1. it is necessary to pay attention to whether the noise of equipment has passed the election to buy industrial boilers. Compared with the domestic boilers, the noise reduction requirements of domestic boilers are lower, but it is still necessary to pay attention to whether the noise of the equipment is too large, to prevent noise pollution and to affect the quality of the industrial environment. In general, the large vibration produced by the boiler noise will reduce the stability of the system, reduce the service life of various accessories, and then reduce the overall life of the boiler.

2. pay attention to the quality of the main material (external anticorrosion or not) the main material of industrial boilers will directly determine its heat resistance. Most industrial boilers use stainless steel outside, try not to choose thinner, lower pressure resistance materials; In addition, it is necessary to pay attention to whether the exterior of the boiler has been treated with anticorrosion. Due to the corrosion in the air under industrial conditions, the moisture content is more, so as to avoid the external corrosion of the boiler and reduce the beauty or corrosion of the core components, thus affecting the normal work of the boiler.

3. pay attention to environmental protection, energy-saving how to usually industrial boilers to run 24-hour round the clock, so we must pay attention to its environmental protection when selecting and purchasing, to avoid excessive power consumption to generate a large amount of electricity costs; In addition, it should also pay attention to its environmental protection, especially in areas with strict environmental requirements, should choose the best environmentally friendly industrial boiler equipment.

4. pay attention to whether there are safety protection devices (such as overtemperature and pressure alarm systems) most of the modern high-end industrial boilers use automatic control, especially when choosing and purchasing whether there are safety protection devices, such as whether there is an automatic water supply system, Anti-dry fire protection, over-temperature alarm, over-pressure automatic pressure relief, which plays a decisive role in the use of safety, do not ignore this problem when purchasing.

To comprehensively promote the prevention of air pollution control work, steadily enhance the quality of atmospheric environment, located in the northern part of Heilongjiang Province held a mobilization meeting Sunwu out of small coal-fired aerated autoclaved concrete cost comparisons to May 7.

Conference announced the "2019 Sunwu urban area out of 10 tons of steam per hour and coal-fired boiler embodiment."

To promote the elimination of built-up area of ​​small coal-fired boiler work, the relevant departments should strictly follow the higher level requirements, the investigation to find out the use of coal-fired boilers and urban planning area of ​​built-up areas, with their own reality, do a good job to implement; should attach great importance to raise awareness, according to the embodiment and objectives, and take various measures to actively promote the complete phase-out of coal-fired boilers small task; to actively publicize the relevant policies, regulations and requirements to the boiler owners, guided by the responsibility to implement, clear time node . To seek truth from facts, objective science, policy guidance, strict enforcement of the principle, in order to reduce air pollution, improve air quality and protect people's health as the goal, according to the classification regulation, departmental interaction, Duocuobingju, the overall advancement of the process steps to form a government command , business differentiation, market-driven, effective supervision, public participation in new air pollution control mechanisms, to promote the phase-out of coal-fired boilers built-up urban area.

Circulating or Bubbling ?

Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone. The fuel is in contact with the particles and effective mixing and combustion allows good efficiency and low emissions. Typically 97% to 99% of all burnable carbon in the fuel stream is combusted, even hard-to-burn materials. Boiler thermal efficiencies can be as high as 87% or more. Although both BFB and CFB systems are effective with biofuels, CFB is especially suitable for large boiler load ranges.

The development of sugar mill biomass aerated autoclaved concrete cost comparison

For many years, sugar mills have burned bagasse, the fibrous byproduct of the processing of sugarcane, using special boilers that produce the steam needed to help break down the sugar cane.
