Abstract

We estimate the emissions of the two most important greenhouse gasses (GHG), carbon dioxide (CO2) and methane (CH4), from the use of modern high-efficiency heat pump water heaters compared to the most commonly used domestic hot water systems: natural gas storage tanks, tankless natural [...]

Abstract

The University of Texas reported on a campaign to measure methane (CH4) emissions from United States natural gas (NG) production sites as part of an improved national inventory. Unfortunately, their study appears to have systematically underestimated emissions. They used the Bacharach [...]

Abstract

In April 2011, we published the first peer-reviewed analysis of the greenhouse gas footprint (GHG) of shale gas, concluding that the climate impact of shale gas may be worse than that of other fossil fuels such as coal and oil because of methane emissions. We noted the poor quality [...]

Abstract

Investigations into direct methane to methanol conversion are justified based on the avoidance of synthesis gas generation, which accounts for around 60% of the capital cost of synthesis gas to methanol conversion. A significant body of information already exists on the process chemistry, [...]

Abstract

In this paper is shown short particular review of the book by the same author “Natural Gas as Heating Fuel”. First criterions for decision of appending on distribution gas network or district heating system for particular part of town are determinate on conditional [...]

Abstract

Natural gas can be directly used for heating of flats by gas distribution system. Indirectly, heating power plant can disburse natural gas and deliver hot water or steam for heating of flats. Decision of optimal way for gas heating usage is done based on spatial disposal of building, [...]

Abstract

This paper presents a review of the boilers according to performed seasonal efficiency. Energy Efficiency Bands are assigned, primarily based on the verified values of seasonal efficiency. In correlation with seasonal efficiency stands annual fuel consumption of a certain boiler, [...]

Abstract

Methodology for calculating Seasonal Efficiency of Domestic Gas Boilers is set by The UK Government’s Standard Assessment Procedure for Energy Rating of Dwellings. This methodology is compatible with EU Council Directive 92/42/EEC on efficiency requirements for new hot-water [...]

Abstract

Gas distributive network in settlements are usually with contours, which assure that gas is available for consumers from few different directions. By application of concept of looped network least possible number of consumers can remain without gas in the case of malfunction in [...]
