High pressure boilers (Powertherm) are mostly water tube boilers in which water is on the tube side while flue gases flow across the tubes thereby transferring heat from flue gases to water using cross flow heat transfer. Thermodyne has a vast experience in manufacturing Water Tube Boilers of a wide range of capabilities that suit the customer needs.

High Pressure Boilers Working:- 
Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell. During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.
Water circulation continues until it’s vapor pressure exceeds the vapor pressure of steam at the top of the drum. At this pressure, water gets converted to saturated steam.Overall, Circulation Ratio is an important factor in designing of water tube boilers. Based on circulation there are 2 basic designs of water tube boilers: Natural Circulation Boilers and Forced Circulation BoilersNatural Circulation Boilers are the type of boilers where water circulates naturally that is due to the density difference. The difference in density is created with the difference in temperature of cold and hot water. Circulation ratio is an important factor in designing of natural circulation boilers so as to prevent the overheating or bursting of tubes.

Water Treatment Chemicals:- 
Water Circulation in Forced Circulation Boilers, on the other hand, does not depend upon the difference in densities but is dependent upon the secondary pump which is installed after the feedwater pump (primary pump) that forcefully increases or decreases the circulation ratio depending on the design and safety requirements.

Construction and Operation of High Pressure Boilers:-
The basic D-Type design of our water tube boilers includes a Furnace enclosed by a set of water tubes which is called a membrane.
The furnace is a part where combustion of fuel takes place. The fuel feeding in such boilers is mostly done automatically either through drum feeders, rotary feeders or screw feeders in case of solid fuels and burners in case of liquid or gaseous fuels.
The furnace is in the high-temperature zone where the radiation heat transfer takes place between the gases and water. From the radiation zone, flue gases enter the convection zone.It consists of convection tubes which are stacked vertically closer to each other, welded at the top and bottom ends to both the water and steam drums respectively.Flue gases in convection zone travel at high velocity across the convective tubes.Baffles are sometimes provided to increase the turbulence. Because of the high velocity of flue gases, convective heat transfer between the flue gases and water increases thereby increasing the overall heat transfer rate.Water drum is placed at the bottom of the boiler while the steam drum is placed at the top.Water feeding is done through the high-pressure pump to the steam drum which has a clear demarcation of water and steam space.

Fuel Used in High Pressure Boilers:
  • Coal
  • Lignite
  • Rice Husk
  • Wood
  • Bagasse
  • Groundnut shells
  • Liquid  and Gaseous (such as Light/Heavy Diesel Oils, Natural Gas)
  • and several other fuels etc.

Combitherm Ultra Boilers (Combi Ultra Boiler) requires minimum site work as they are factory assembled units and is mounted on a skid base frame. Their working is same as our Combitherm model in a way that they too are the combination of water tube design and smoke tube design. Combitherm Ultra model is also a 3 pass design with 1 pass of flue gases in external furnace or membrane which is surrounded by water tubes and 2 passes of flue gases in shell tubes just like the Combitherm Model.The only difference is that it is a compact design and requires less space as compared to the Combitherm design. In this water, tube membrane is many compacts thus allowing minimum or no radiation losses to the surroundings. The shell in the case of the Ultra model is placed just above the membrane thereby reducing the time for water to reach the membrane through downcomers thereby allowing easy and faster water circulation. This mainly prevents the overheating of radiation tubes and eventually increases the operating life of your boiler. In this downcomers are provided on the sides of the shell membrane assembly and riser headers and pipes are provided in between the shell and the membrane.
This unique and compact design can handle almost all type of fuels such as wood, coal, briquettes, rice husk, petcoke etc. Generally Rice husk fuel is fed automatically to the boiler through screw feeder and the bed which consist of sand is made fluidized using high air pressure for this case the height of the boiler is increased to some extent to ease its operation while in case of other fuels such as wood, coal, petcoke etc boiler can be placed at normal heights without affecting its operation.

A Boiler Chemical is used for generating steam. The primary function of a boiler is to transfer heat from hot gases generated by the combustion of fuel into water until it becomes hot or turns to steam. Boiler feed water often contains impurities, which impairs boiler operation and efficiency. As more and more steam is evaporated, the water becomes more and more concentrated with salts and other impurities. These are usually Calcium or Magnesium salts which on concentration, form scales or deposits. These scales are very damaging to the boiler because they interfere with the heat transfer and can lead to overheating and eventually, boiler rupture. Thermodyne chemical additives can be used to correct the problems caused by these impurities. To improve feed water quality, and steam purity, these chemicals can be injected directly into the feed water or steam.

Benefits of Thermodyne Water Treatment Chemical:
  • Increase boiler efficiency
  • Reduce fuel, operating and maintenance costs
  • Minimize maintenance and downtime
  • Protect equipment from corrosion and extend equipment lifetime
