Boiler Supplier

(4) The water level gauge and the safety valve fail, and the boiler cannot be operated safely.

(5) When the drain valve fails and the control valve is closed tightly.

Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boilers to cook fish industrial. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.

Gas-fired power plants are an important part of China's power industry. The use of water in the power industry is multi-faceted, including boiler replenishment, cooling water, and miscellaneous water for life. The most stringent water quality requirements are boiler replenishment water. Nowadays, thermal power plants are developing towards large capacity and high parameters. The water quality of boiler water is also getting higher and higher. The boiler water quality requirements are very strict, not only requiring low hardness, dissolved oxygen. Very small, solid content and organic content are also very small, water that does not meet the water supply standard will make power plant equipment unable to operate safely and economically, so in addition to conventional coagulation, sedimentation, filtration and other water treatment methods, ion exchange is required. , complex bed, mixed bed, reverse osmosis desalination treatment system, electrodialysis and other softening, desalination high purity water system, ultrapure water treatment equipment technology to treat super high pressure boiler feed water in thermal power plants. To this end, quality indicators for various water uses in thermal power plants have been developed.

Structural features angle tube boiler:

1. boiler self-supporting structure, i.e. the lower part of the drum through a large diameter drop across the tube support in the lower portion, no separate frame support or suspension, also known as non-framework boiler;

2. The use of membrane wall, the furnace is integrally welded into a water-cooled wall box, air leakage can be reduced, without heavy refractory brick and insulation;

3. The drop tube connected to the lower header supply pipe, as well as soft drinks and drum upper header pipe connected to the lead, does not use a large bending radius, and welded to the pipe with a small radius bend wrought the boiler compact structure, it is simple;
