CENTRALIZED WATER HEATING SYSTEMS- 01. SOLAR ENERGY

Solar energy is one of the widely used renewable energy that can be harnessed either by directly deriving energy from sunlight or indirectly. Solar water heating system, on the other hand, is one of the applications of solar energy that has drawn great attention among researchers in this field. Solar collectors, storage tanks and heat transfer fluids are the three core components in solar water heater applications. The latest developments and advancement of a solar water heater based on the three basic components that may affect the thermal performance of the system. VERSOL reviews the development of various types of solar collectors in solar water heater, including both the non-concentrating collectors (flat plate collector, evacuated tube collector) and the concentrating collectors (parabolic dish reflector, parabolic trough collector). All these are studied in terms of optical optimization, heat loss reduction, heat recuperation enhancement and different sun tracking mechanisms

Renewable energy Solutions for Water Heating

There are a number of ways you can generate your own energy at home from low or zero carbon ‘micro generation’ technology. Making your own energy, instead of using mains gas and electricity, will reduce your carbon footprint. Solar Panels Solar panels harness the power of sunlight to heat your home and hot water . An in-house display will allow you to see when energy is being generated, enabling you to make the most of the free power - for example, by running your washing machine at these times. Any extra energy you generate but don't use will be sent to the National Grid, which you'll get paid for. But there are a lot of factors to consider, such as the cost of the installation, and whether your home is in the best position to harness the power of sunlight. Solar thermal panels generate heat. Solar photovoltaics (PV) generate electricity. Wood-burning stoves Wood-burning stoves aren't cheap to install, but the heat a stove generates can mean you don't hav

ARE YOU MAINTAINING YOUR BOILER WELL, IS IT WORTH SPENDING?

The boiler is one of the most intensively used household / industrial appliances, but unless the heating suddenly stops working or your water won’t warm up, faults can go unnoticed. A  boiler  breakdown can be frustrating and costly, especially if you’re in the middle of winter. But certain failures can also be a danger to you if not spotted in time. Regular maintenance should help keep your boiler running smoothly. But, like most machines, unexpected issues can always crop up. When they do, unless you’re a gas engineer, it’s not always easy to know when to take action. 1)    RADIATORS TAKE LONGER TO HEAT UP Do your radiators stay tepid or take hours to get hot? This could mean that your boiler is on its way out. Most modern boilers can reach their maximum temperature quickly and produce heat almost instantly. But it could also mean your heating system is filled with sludge – this causes blockages and cold spots on your radiators. Dirty water circulating in the system could resu
VERSOPUMP- Versol Heat Pumps : Advantages and Disadvantages VERSOPUMP Heat pumps  represent systems that ‘pump’ or move heat from one place to another by using a compressor and a circulating structure of liquid or gas refrigerant, through which heat is extracted from outside sources and pumped indoors. Pumping the heat uses less electricity as compared to when electricity is solely used as a means to convert it. During the summers, the cycle can be reversed and the unit acts like an air conditioner. Heat pumps represent the most efficient alternative to fuel, oil and electric systems in regards to both heating and cooling. Gas furnaces do a relative good job, rated close to 98 per cent efficient, however they do not represent a long term solution from a carbon footprint aspect. Heat pumps supply more heating and cooling capacity than the amount of electricity used to run them. Properly designed and installed heat pumps regularly attain more than 300 per cent efficiency.

FIRE TUBE BOILERS- WETBACK & DRYBACK

Boiler is a closed vessel that is used to produce steam at desired pressure.There is a reversal chamber for flue gases between 1st & 2nd pass is provided inside the boiler shell, Based on this reversal chamber boilers are differentiated into Wetback and Dry-back. In dryback boiler rear wall is lined with refractory. In dryback boiler reversal chamber has a rear wall that is lined with refractory, which passes combustion gasses from the furnace to multiple tube sheets and resulting in radiation losses.The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access. Dryback boilers also require regular refractory and tube sheet inspection, which can be costly maintenance items. Wetback boiler designs have a water gap between the furnace and back wall, Hence the radiation losses due to refractory lined reversal chamber in the back end smoke box are eliminated as the complete heat of the furnace is transferred to the water i

CORROSSION- Cannot be neglected in Heating /Boiler System

What is Corrosion?-  Oxidation is the reason for Corrosion. Oxygen content in the water or air in the system reacts with metal to form oxides which eat up the body resulting in formation of Cavities and holes. A.      Corrosion in Boilers A1. Reasons for Corrosion in Boilers ·        Improper and unscheduled maintenance in the system Timely maintenance is required to prevent the corrosion in Boilers and Hot Water Systems ·        Non treated Feed Water in Boiler System If the feed water is not treated, removed oxygen from the water will accelerate corrosion ·        Oxygen or Carbon Dioxide present in Water ·        Unbalanced pH- Water Shall be maintained Ph value as recommended Periodic maintenance and Water treatment is essential to control corrosion in Boilers B.      Corrosion in Storage Units Normal Heating Systems are provided with Storage units to cover the hot water peak demand. Storage units ( Calorifiers ) are normally offered with Corrosion resistiv
