Drying in textile industry - Efficiency Finder

2017-10-9 · A few units are indirect gas fired but their efficiencies are poor when compared to direct fired systems. Gas fired stenters are highly controllable over a wide range of process temperatures. Thermal oil heating is another method. But this requires a small thermal oil boiler (usually gas fired) and all its associated distribution pipework.

FAQs - Fernox UK

The damaging effects that limescale can have on the lifespan of a boiler and the energy efficiency of a central heating system are significant. Part L of the Building Regulations stipulates that where mains hard water exceeds 200 ppm, feed water to water heaters and the hot water circuit of combination boilers must have a scale reducing device

EP0640747A1 - Boiler system pH/phosphate program

A pH/phosphate program in a boiler water system is controlled by: (1) determining the feed rate of the phosphate to the boiler by adding to a phosphate-feed stream containing the phosphate feeding to the boiler a phosphate-feed tracer in known proportion to the phosphate, determining the concentration of the phosphate-feed tracer in the phosphate-feed stream and correlating the phosphate-feed

Is a super high efficiency boiler worth the inital cost

2009-4-23 · Using batteries the efficiency is less but probably reduces propane use for the outage. Propane is the most expensive fuel at this time. But, the wife wants a gas stove, the best fuel for an engine (i.e. generator) is natural gas or propane, propane does not get "stale", low temperatures do not affect it, it burns very clean in the boiler (so

What is a Combi Boiler & What Size Boiler Is Best For

With a combi boiler, the water is fed from the mains so the water pressure is generally greater. This boiler type is one of the more high efficiency boiler systems available and at a price that fits most budgets when it comes to the right boiler cost, installation costs and overall energy bills moving forward.

Water-Cooled Condenser - an overview |

Water-cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water. The most common type of water-cooled condensers in geothermal power plants are direct-contact and surface types. Plate-type heat exchangers (a special kind of surface exchanger) are also possible, but appear to be more common in liquid-to-liquid heat transfer applications.
