The deep matched technology of new combustion and heat transfer no longer sacrifices the boiler's key characteristics to adapt to the burner characteristics, making the gas boiler a complete thermal system with low nitrogen emissions.

The advantage of the electric heating steam boiler is that there is no combustion chamber and no chimney is needed, so the heat loss does not have to be considered, and the thermal efficiency can reach 98% or more.

This series of boilers adopts the design structure of full-membrane wall, and the sealing effect is very good. Multi-layer insulation materials are laid in the transmission pipeline and welding place to minimize the heat loss of the furnace body.

Jun 28, 2019 · The natural gas used in gas boilers is mainly composed of methane gas and contains a small amount of non-hydrocarbon gas. Generally, it does not contain water and ash. Therefore, it mainly produces carbon dioxide and water after combustion, and releases a large amount of heat.

When evaluating the prospect of converting a coal-fired boiler to natural gas, there are a number of factors that need to be independently evaluated. The combustion system modifications and boiler performance impacts are several important aspects to be considered. The combustion system

The idea of converting an existing coal-fired boiler to natural gas-firing is not new. The MIT Energy Lab published a report reviewing the feasibility and cost of such a conversion in 1986 with the ultimate goal of reducing sulfur oxide emissions. 1. Today these conversions are being revisited as an alternative

The use of natural gas in coal-fired boilers, IEAPER/35. There are three main options for integrating natural gas into coal-fired boilers: - fuel staging (reburn) for NOx control; - cofiring of coal with gas in existing boilers; and - integration of a natural gas turbine with an existing coal-fired boiler to form a high efficiency combined cycle.

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
