Recently, the Weifang Municipal Quality Supervision Bureau investigation work for power plant hotel pressure fire tube 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.

In the two oil crises of the 1970s, natural gas was used as a fuel for hotel pressure fire tube boilers.

By the early 1990s, fuel-fired industrial boilers with a certain degree of technological development had a high market share in the boiler market.

The CFB hotel pressure fire tube boilers will replace typical pulverized coal (PC) units that are outdated and worn out. Combustion of high-ash anthracite in the CFB boilers is inefficient, requires considerable co-firing of natural gas and produces high SOx and NOx emissions. The important boiler design and performance parameters, such as furnace height, fuel and limestone sizing, solids recirculation rate, combustion efficiency and emissions performance, were developed using the results of high-ash anthracite pilot CFB testing.

Differences in the functions of different types of gas-fired hotel pressure fire tube boilers

Each boiler uses different fuels, some burning with coal, some with fuel or gas, some with electricity, and some with coal-water slurry as the raw material for combustion.
