When determining how much space should be between steam boilers, serviceability should be at the top of your mind. Sure, you want to save space, but you also want to make sure you have plenty of elbow room to service your boiler properly.
One of the most crucial factors that will determine how you space your boiler units is whether your boiler system is being installed in a new construction facility or an existing building that is being retrofitted.
While a new construction giv...
To guarantee the successful and efficient shell boiler operation, the user must:
1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer.
2)Provide a boiler house layout and installation that promotes good operation and maintenance.
3)Select the control systems that allow the boiler to operate safely and efficiently.
4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s).
5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
The combustion method of the boiler equipment is also a factor that the majority of users will consider when selecting the boiler. Depending on the combustion method, the boiler structure and boiler room layout will be different.
According to the differences in fuel and structure, industrial thermal oil heaters are mainly divided into the oil/gas-fired thermal oil heater and coal/biomass-fired thermal oil heater. The basic configurations of the thermal oil boiler system generally are as follows.
The safety valve of the boiler refers to the valve on the top of the boiler near the boiler control room. The function of the safety valve is to be opened automatically to exhaust the steam and restore the pressure when the boiler pressure exceeds the specified valve, so as to ensure the safety of boiler pressure-bearing components and steam turbines.
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.
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.
