The flue gas first enters the cyclone dust collector which acts as a primary dust collector to make the large dust particles in the flue gas settle down. The cyclone dust collector is a dust removal device which uses the centrifugal force generated by the cyclone flow to separate the dust particles from the air flow. Afterwards, the flue gas enters the wet scrubber dust collector which is a circular-type cylinder. The circulating water enters the dust collector from the upper overflow tank to form a uniform water film on the inner wall of the dust collector. The flue gas is induced tangentially or spirally from the lower part of the cylinder and rotates in the cylinder. Under the influence of the centrifugal force, the dust particles are separated from the flue gas and then the flue gas is also spirally led out from the top of the cylinder. The dust particles are thrown to the water film, transferred to the bottom and finally discharged from the dust port.
Boiler is a piece of equipment with large energy consumption. Therefore, both boiler manufacturers and purchasers regard energy conservation as an important indicator of boiler performance. The daily energy-saving measures of the natural gas fired boiler are mainly as follows.
The vertical type and horizontal type are the two main types of boiler. The vertical gas-fired boiler has small volume and is suitable for small workshops or small production enterprises. It is often used in the fields of hot water and heating. The horizontal gas-fired boiler has larger volume with a wider application range than the vertical gas-fired boiler.
The high heat transfer of the boiler requires good medium. With the improvement of boiler in the production technology and intelligenlization, gas-fired boilers have more strict requirements for boiler operation medium in order to improve the boiler operating performance, reduce boiler failures and costs.
Due to the development of boiler technology and relevant policies, gas-fired boilers using eco-friendly fuels are often applied for heating. For thermal power companies, cost is the most important issue.
The dual-fuel boilers usually burn oil and gas fuel which can be natural gas fuel or artificial gas fuel such as natural gas or diesel. The field-assembled dual-fuel boilers also burn the heavy oil or light oil. This type of boiler can make enterprises select the fuel more flexibly and minimize the boiler operating and production costs for enterprises.
It is inevitable for gas-fired boilers to produce noise including heat exchange noise, aerodynamic noise, mechanical running noise and other noise after ignition.
When using the industrial gas-fired boilers, daily boiler operation and management should be paid attention to ensure the safe and stable boiler operation, so as to guarantee the daily production of workshop.
