Professional, efficient, industrial boiler supplier.
The exhaust flue gas from natural gas boiler(NGB)contains a lot of sensible heat and latent heat,and recycle and utilization of the heat can significantly improve energy efficiency.Based on the heat features of NGB flue gas,a new heat recovery system was proposed
A 15% saving on a gas spend of £1,200 per year would save £180. If gas energy prices rise sharply, the saving with a new, high efficiency boiler would be higher too. Still, shorter showers, slightly smaller baths and slightly cooler houses could save more. A shower from a combi boiler (at 2018 UK gas prices) costs about £1.40 for each hour.
2019-8-5 · Online calculator to quickly determine Boiler Efficiency. Includes 53 different calculations. Equations displayed for easy reference.
2019-10-7 · Small boilers, including natural gas-fired boilers and those without soot blower systems, should be opened regularly for checking and cleaning. Deposits (called scale) on the waterside of the boiler tubes can impair heat transfer. They can also reduce boiler efficiency, restrict water circulation and lead to serious mechanical and operating
According to the ASME Energy Balance Method of calculating industrial boiler efficiency, you should account for convection losses, radiation losses, and stack losses. However, you should dig a little deeper to understand the factors that directly affect these important readings, which ultimately affect industrial boiler efficiency.

A hot-water radiator heating system is a type of central heating. In this system, heat is generated in a boiler. For the generation of the heat, a natural gas boiler is used where the chemical energy of natural gas is transferred into the heat. Then, the heat is distributed by hot water (heat carrier) to the radiators.
2018-3-28 · natural gas, NOx formation through the fuel NOx mechanism is insignificant. Carbon Monoxide - The rate of CO emissions from boilers depends on the efficiency of natural gas combustion. Improperly tuned boilers and boilers operating at off-design levels decrease combustion efficiency resulting in increased CO emissions.
2019-10-8 · Convert to a dry gas basis using the following formula for natural gas: O 2dry = O 2wet x (1.222 - 0.012 O 2wet)‚ % Obtain the CO 2 ‚ % by volume‚ dry gas basis. When firing any given fuel the amount of CO 2 in the flue gas is related to the amount of O 2 in the flue gas. For natural gas‚ the relationship is defined by the following
