Natural gas was chosen because it is one of the least contaminated fuels used for boiler operation. It does not generate any dirty emissions or cause an unpleasant odour when burning. It is an eco-friendly alternative. This type of gas is steady and reliable, supply is seldom disturbed, even when demand is high, unlike electricity or oil.

Since the natural gas only has to be pre-heated to moderate temperatures, usually only to approx. 100 °C or less before being expanded, various heat sources can be used for this purpose: district heat, industrial waste heat, heat from hot water boiler plants and combined heat and power plants.
2018-2-17 · Dimensioning of CHP units up to 2 MW el Following information helps to determine approximate values for a first estimate of the appropriate CHP dimension. They are based on long experience, cover a wide spectrum of applications and apply for gas engine CHP units which work at a heating water level of 90/70°C.
2013-12-23 · Domestic heating by gas: boiler systems – guidance for installers and specifiers (2008 edition) 5 Introduction to best practice 1.3 Environmental impact of gas heating Gas relative to other fuels The main environmental impact of heating systems is the emission of CO 2. The CO 2 emissions from burning natural gas are low in comparison with most
2020-7-24 · Since the natural gas only has to be pre-heated to moderate temperatures, usually only to approx. 100 °C or less before being expanded, various heat sources can be used for this purpose: district heat, industrial waste heat, heat from hot water boiler plants and combined heat and power plants.
Extra CO 2 to augment the level inside the greenhouse can be sourced in a number of ways, including exhaust gases from heating and, less frequently, the administration of pure CO 2 purchased commercially.. However, CHP makes it possible for the required CO 2 to be obtained from the exhaust gases of a gas-fueled engine. This becomes viable once certain components of the gases have been
Plants grow by converting CO 2 to carbon through photosynthesis. Air generally contains approximately 350 ppm CO 2.Optimal CO 2 levels depend on the type of plant and generally lie above 700 ppm. With increased artificial lighting, as present in greenhouses, plants absorb even more CO 2.If the greenhouse atmosphere is enriched with CO 2, the temperature kept on a constant level and sufficient
2014, Incorporation study on the municipality's natural gas and district heating operations 2014, Location study of biofuel heating plant Study on the dimensioning of the boiler in order for it to produce 95 – 98 % of annual district heating production with biofuels.
The products of combustion of natural gas include carbon dioxide and water vapor. In a conventional boiler, the flue gas temperature is kept above the flue gas dew-point (roughly 140 F) to prevent the water vapor from condensing in the boiler or exhaust stack and
2016-12-20 · Natural gas is more than 90 % methane (CH 4) with ethane and a small amount of other hydrocarbons; inert gases such as N 2 and CO 2 may also be present. Gas flaring from refineries and other process operations will commonly contain a mixture of hydrocarbons and in some cases H 2. However, landfill gas, biogas or digester gas
Dimensioning of the boilers. Study for connecting natural gas; Study for dimensioning and installing the chimney. Study for constructing an RF room for locating the boilers. Study for the integration and hydraulic connection of the boilers to the existing system. Analysis of the offers. Direction of the works

Italtherm is an Italian manufacturer of condensing and traditional wall hung gas boilers, for independent and central heating. Condensing boiler up to 35 kW, with modulation ratio from 1:10 to 1:20: the maximum about high-tech, design and efficiency. Italtherm has developed a set of configurators to assist importers to realize the
2021-3-3 · The upgraded thermal design with optimized flue gas oxygen content ensures a total efficiency of 89–92% depending on boiler load conditions, which is in average 6% above the typical boilers in this capacity range. This means less fuel consumption and lower CO 2 and NOx emission levels. On a 16,000 kg/h boiler operating 5,000 hours at 75% load
2020-3-25 · A 130 metre high boiler at a coal-fired power station is a sight to behold. Towering over its surroundings, it gives an idea of the scale of engineering that goes into large industrial projects. The Medupi power station in South Africa has six of these boilers. And it's also the largest construction project in the southern hemisphere.
A smart gas condensing boiler which is designed to heat up domestic water directly is connected to a storage tank. For water harder than 11°dh water can be heated indirect using a spiral flat heating coil in
