Advantages and disadvantages of central heating. Investing in a central advanced energy efficient boiler/ furnace can provide more effective space heating. Control is better/energy use reduced when rooms have individual thermostatic control and all are turned on and off from one location. Gas or renewable energy can be used, and air conditioning can also be included.
Advantages of PC vs. stoker boilers: • much quicker response to changing loads • lower excess air/higher efficiency • easily adaptable to automatic control • can burn wide variety of coals Disadvantages of PC vs. stoker boilers: • more expensive (at least for smaller capacities)

Control of Boiler Operation using PLC – SCADA K. Gowri Shankar Abstract––This paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully automated boiler. Over the years the demand for high quality, greater efficiency and automated machines has increased in this globalised world.
The advantages of a packaged boiler are: 1. Lower freight costs because of less handling 2. Lower initial cost because they are mass produced 3. Quality control is easier to implement 4. The boilers can be factory tested before being sent to the customer 5. It requires …
So far, the steam generator is controlled only by manually. Now the process is fully automatic and analysis of status obtained in SCADA. Applying Steam is controlled by PLC. So, efficiency of heating the boiler by use of steam is to be high. 1.3 Control Parameters In Boiler 1. Level Control 2. Pressure Control 3. Flow Control 4. Temperature Control
The boiler-turbine unit control schemes have gone through several decades of evolution and, typ-ically, a cascade of PI/PID controllers based on single-input single-output control loops is designed in the plant to fulfill such tasks.6,7 The remain-der of this section will focus mainly on the con-ventional boiler-turbine coordinated control system
Automatic pellet boilers offer zero-maintenance combustion of pellets. The rotary burner with a self-cleaning combustion chamber enables the combustion of pellets of lower quality. Advantages of the pellet burner with rotary combustion chamber: Internet system ecoNET provides to user option for remote control of the boiler and heating
