What are the developing trends of condensing repir plate of wet back boiler design

It is well known that condensing gas-fired boilers have higher boiler conversion efficiency and can save a lot of energy. The design and development of this condensing boiler brings a better direction for the utilization and rational disposal of clean energy in our country. And in view of the application demands and technical standards of all kinds of natural cleaning materials in our country now, it can also be found that the design of condensing boilers also needs to be optimized with the trend of the times. The following is a brief introduction to the development trend of condensing boiler in our country.

What method of industrial repir plate of wet back boiler feed water treatment for industrial boiler feed water treatment methods are what? Treatment agent tank features are: small (1) investment, low cost, easy operation; (2) a chemical treatment combined with the outer tank, may further eliminate residual hardness; (3) environmental pollution; (4) can not be completely prevent boiler scaling; (5) water hardness inappropriate. The main method of treatment of the pot are: 1) salt method. Commonly used is trisodium phosphate, sodium carbonate (sodium carbonate), and fire (sodium hydroxide), which is the most common soda. 2) Integrated scale inhibitor law. Sodium hydroxide, trisodium phosphate, sodium carbonate and tannin extract composition Comprehensive inhibitors. Potting, there are two methods: one is administered intermittently, is continuous administration of two kinds. 3) an outer pot chemical treatment. The use of auxiliary water treatment equipment, boiler water softener recharge to ensure that qualified and softened, desalinated water.

Henan gas repir plate of wet back boiler to start the process of how to control the drum water level during startup Henan gas boiler drum water level should be adjusted according to changes in the status of kotelshchik control. (1) the initial ignition, Henan gas boiler pot of water gradually heated, vaporized, expanded, the water level rises, this time not by accident turn on the water to reduce the water level door, and the door should be regularly sewage discharge, can increase the pot of water quality, and promote water cycle. (2) With the increase of steam pressure, steam temperature, the amount of exhaust is increased according to the trend should drum level, replenish the water supply. (3) performing Henan gas boiler when the red tube or security check gate, often due to a sudden increase in steam flow, steam pressure and cause serious downhill "false water level" and, therefore, should be preceded by performing the above operations remain low water level, and then increase the water supply according to changes in the flow of steam, causing the water level is too low to prevent the safety valve seat and other reasons. (4) The load condition Henan gas boiler, the feed line switching operation in a timely manner, and in accordance with a predetermined condition, into the automatic water supply device is operated.

The party hot water repir plate of wet back boiler output fast enough to provide high efficiency, give us save a lot of fuel costs, and exhaust gas discharged tested in full compliance with environmental regulations on emissions of air pollutants in Henan Province. Fast boiler responsible attitude also left us with a deep impression, overhaul maintenance problems for a number of aspects of boiler operation and post, sent a very professional technical staff and our butt, fireman guide our people, for the quick sale of party, we are also very satisfied. --customer feedback
