And condensing boilers generally use clean energy such as natural gas as a fuel, has great environmental protection. In addition, the condensing boiler also has other advantages, with a look. A modular operation more simple design using a condensing boiler combined into a plurality of sections of the design pattern, the mounting structure is simple, the use of flexible and convenient. Simply refers to: split the original single large boiler dry N plurality of small boilers. This design allows the boiler by the number of "simple parallel combination" may reach the size of any single boiler, so many users choose this status condensing boiler to replace the various types of heating and hot water boilers. Second, to reduce maintenance costs condensing boiler heating system boiler, including its internal control system and automatic gas control system, no working system can achieve a high degree of artificial effect, greatly reduces the labor costs. And condensing boiler through continuous optimization of design, process design condensing boiler, matching equipment level to a new level, to enable them to better serve the industrial production. Third, due to the smaller footprint smaller storage capacity of a condensing boiler, the temperature of heat up very quickly, only a few seconds, without generating excess heat loss. And because of its small storage capacity, so that the condensing boiler smarter structure, small volume, light weight, even if it is placed in the roof is also very convenient. And the use of condensing boilers can also save investment investment.

The picture shows the sawing unit is a sectional view of the conduit, the pipe can be seen the situation is collapsed. Wall thickness of 0.8mm, 0.6mm as the gap between the tube (in accordance with the requirements of corrosion resistance to low temperature, at least the wall thickness should be above 0.8mm, a gap between the tube should be at least 0.6mm or more). The wall thickness between the main heat exchanger tubes and the gap just meet the basic requirements, far from good design standard, which is due to the pressing pressure, the time between the constant pressure, wall thickness, material resilience, cost, and slit width mutual check and change, so that manufacturers must be able to select a balance in all aspects of parameters point, it can not be the best in all-round standard. The diameter of dust fly ash produced after the combustion boiler usually 500 microns (0.5mm), but due to adsorption of acid such that a plurality of fly ash (fly ash for the initial fluffy, bulky, easily adsorbed acidic substance) adhesion occurs, forming large flowers fly ash particles. If the gap between the pipe is too small, it is easy to cause plugging ash.

When determining the bath boiler, it is not necessary to determine the boiler capacity. The boiler fuel, boiler pressure, boiler type, etc. also need to be determined. Bathtub boilers are designed with a wide range of content and often need to be delivered to professionals to determine.

Recently, the Weifang Municipal Quality Supervision Bureau investigation work for power plant boilers, boiler pipes mainly the situation, avoid boiler due to pipeline damage caused by explosion or other accident, serious economic losses and social impacts.

Quality Supervision Bureau adhere to problem-oriented, carefully study and strictly enforce the AQSIQ and the Provincial Quality Supervision Bureau of the requirements for the range of power plant boiler pipeline design, manufacture, installation, inspection, management and regular inspection of the use of accurate knowledge boiler safety awareness the importance of strengthening the red line awareness, risk awareness and responsibility to play, continue to maintain high pressure, strengthen safety supervision work of the power plant boiler tubes.

Bureau of Quality Supervision focus on checking whether the boiler tubes carry out regular inspections in the construction of power plant boiler accessories combination whether to implement supervisory inspection of manufacturing, installation work unit level meets standard requirements, flow meter housing if there is a security risk, whether the use of units developed power plant boiler tubes emergency plans and emergency rescue exercises, in a timely manner to improve the problems found.

To date, Weifang City inspectors were deployed 257 times, check the power station boiler unit 58, checking in with a number of boiler 193 units, eliminate safety hazards 78.
