Professional, efficient, industrial boiler supplier.
The boiler is where the energy conversion from fuel to steam takes place. The steam is used for power production, for a process reaction, or for heating another fluid or gas, or simply for heating the air in a building. By boiler efficiency, we mean the efficiency of conversion from the chemical energy in the fuel to the heat energy in steam.
2018-1-4 · BOILER EFFICIENCY / TEST DETERMINATION. We carry out boiler efficiency tests as per DIN 1942 standards, with our set of equipments. Both direct & indirect test are carried out. In direct test, actual fuel fed & water evaporated are measured whereas in indirect method. O2%, CO2% stack gas temperatures, ash loss, wet gas loss are determined.

1 · Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters
The thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side. Thermal efficiency is badly affected by scale formation/soot formation on the boiler tubes. But direct efficiency can only tell us about the magnitude of overall loss. No
2012-10-19 · Z. Kadlec et al. 88 Fig. 1 Comparison of specific heat capacities determined according to values given in the tables, according to ČSN 07 0302 and according to DIN 1942. (on axis x – temperature of waste gases ( oC), on axis y - c sp (kJ.m –3.K-1). Fig. 2 Comparison of looses by heat sharing with the environment according to ČSN and DIN at various rated outputs of the boiler.
The boiler efficiency, obtained through this proposal, is determined from the sum of all heat loss fractions, Eq. (17). In this work was considered, for both proposals, besides the heat losses mentioned above, the heat loss by bleeding in boiler (q 7). This heat loss was considered corresponding at 2% of boiler steam mass, according .

2011-5-2 · Fluegas heat loss Heat delivered to the ambient air because flue gas has higher temperature than initial or ambient one. In all of the cases this is the largest loss, which determines mainly the boiler efficiency. At an up to date boiler it is generally in between fg = 5 - 10 % At earlier constructions it is in between fg = 10 - 15 %
