Third, in the boiler unit will be the safety management system, emergency plans to check the system; and to convey the importance of this inspection in the boiler unit, raise awareness of security units.

Fourth, strengthen supervision of energy-efficient boilers, boiler and actively promote energy efficiency testing, at present, boiler energy efficiency testing has been completed a total of 112 units.

To date, the Longhai inspection operations were dispatched inspectors 209 passengers, checked boiler unit 136, check the boiler 168 units, eliminate safety hazards at 9, and urge the use of sealed units to enhance the energy efficiency of boilers 21 units.

And with the Commission by letter, and environmental protection departments to further promote the comprehensive upgrade of coal-fired boiler energy saving project, disable the coal-fired boiler 53 units, 34 units scrapped, replaced by raw material boiler fuel and natural gas fuel of a total of 40 units, is out of the city coal-fired boilers to make a positive response.

3 pressure, gas accessories of steam boiler

Rated working pressure of the boiler steam pressure should be greater than the sum of the boiler plate steam supply pipe resistance and operating pressure needed for the production. Do not overlook the steam pipe resistance, due to its higher rated steam pressure saturated steam temperature is higher.

On the hot water boiler which will have its scale hot water accessories of steam boilers in use, may cause problems such as scale, once the scale, then we should be immediately removed, so as not to impact the normal operation of the boiler. However, not a single kind of scale, we must first look at what kind in the end there will be, so as to more targeted and better to clear it out. Torch burning industrial equipment on to explain what kind of hot water boiler scale what its contents are as follows. Hot water boiler scale in general, these are the following: 1 carbonate scale: its main component is calcium carbonate and magnesium, but is mainly calcium carbonate, which is generally white color, which produces parts, mainly in some relatively low temperature site. 2. sulfate scale: its main component is calcium sulfate, is relatively hard and dense, white or yellow color, which appears parts, mainly elevated temperature strength and evaporated in a relatively large evaporation surface. 3. silicate scale: its composition is more complex, silica and the like, which is very hard texture, off-white color is mainly present in the boiler heating surface strongest parts. 4. Mix scale: scale and mixtures of these types is the rust, which has a plurality of colors, and a multi-layered form, which is not fixed portion occurs.
