valves for steam boiler of sulphuric acid plant

Hot water boiler heating industry is our essential equipment, gas hot water boiler water provided by the party fast flotilla, high thermal efficiency direct savings on fuel costs of inputs for our company, the intelligence facilities let the boiler run more convenient and effective to reduce the labor intensity of fireman people. --customer feedback

Of course, not only it is the case, and now some of the plants because of the need to use large amounts of steam, so start now with the emergence of a valves for steam boiler of sulphuric acid plant, this boiler equipment, is mainly used to provide steam, allowing the plant at the time of production using the steam needed, which can now contribute to the production plant.

Gas hot water boiler heating method which clean gas hot water boiler after a long run, will gather a lot of dirt; if not promptly cleaned up, it will seriously affect the operation of the boiler and heating effect. So, faced with the dirt, how do we deal with it? Calcium and magnesium salt ions softened water treatment for water, soft water treatment can be effectively eliminated, i.e. the softening sodium ions. , The water is softened by the addition of a certain proportion of the drug. + Even given row sewage water discharge is a very important part of a gas boiler, and its role is obvious. Whether the excess salt or regular sewage discharge can effectively discharge the boiler water continuous. Practice has proved that the stain cleaning, chemical cleaning and mechanical cleaning is an effective treatment. Some people think that, after the heating system is an effective soft water facilities installation, no bother cleaning, which is inconsistent with the actual situation. Both softened water treatment, and with the correct cleaning method is the most effective and thorough approach.

Ensure the safety of boiler what issues need attention? Boilers, regardless of tonnage, are energy conversion devices, also belong to special equipment for this, will have the State Council promulgated the "Regulations on Safety Supervision of Special Equipment", because of its security and stability is a basic principle of its operation, otherwise It will cause great loss, because, boilers should be used in strict accordance with the relevant regulations execution: 1, boiler factory should be accompanied by "technical safety specifications of the design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate ( safety supervision, inspection and performance certificate); 2, boiler installation, repair, alteration in the boiler installation, maintenance, transformation of the units shall obtain special equipment installation and maintenance certificates issued by the provincial quality and Technical supervision, before engaging in the boiler installation , maintenance, renovation. construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the municipality or the area of ​​special equipment safety supervision and management departments, and will start informing sent to the local county level quality and Technical supervision for the record, you can informed construction; 3, boiler installation, maintenance and inspection of facilities renovation After the completion of the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic test of the boiler installation supervisory inspection declaration after passing by the state Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance.; 4, registration boiler after the boiler inspection, the unit must be in accordance with the use of "special equipment registration and use of management rules", fill "boiler (census) registration Form", the state quality and Technical Supervision to register and apply for "safety registration certificate of special equipment"; 5, operation of the boiler boiler must be qualified by trained, made "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and system of eight, six. records;.. 6, test boiler boiler periodic inspection every year, not be used without safety periodic inspection of boiler safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, without periodic testing security accessories may not be used; 7, non-pressure boilers will be installed to the boiler pressure is strictly prohibited. With a water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.

Low Temperature Corrosion in Boiler and Its Prevention

Boilers generating steam for use in power generation and process power plants use different type of fuels. These fuels contain sulphur to differing percentages. The higher the percentage of sulphur, the higher will be the risk of cold end corrosion in the boiler. The sulphur in the fuel during combustion gets converted to sulphur dioxide.
