Boiler efficiency refers to the percentage of boiler effective utilization heat to boiler input heat per unit time, that is, the percentage of effective utilization heat per standard cubic meter of gas fuel. ZOZEN gas-fired boilers all adopt large furnace design, with the efficiency as high as 98% and NOx emission as low as 30mg/Nm3.
Drum boiler refers to boiler equipment with boiler drum, which is an important pressure component in natural circulation boiler and the connecting hub of the three processes of boiler heating, vaporization and overheating, and plays a connecting role. Water becomes qualified superheated steam in the boiler, which goes through three processes: heating, vaporization and overheating. Heating from feed water to saturated water is a heating process; The vaporization of saturated water into saturated steam is a vaporization process; Heating saturated steam into superheated steam is an overheating process.
With the continuous development of economy, as the main heat energy equipment, industrial boilers are widely used. This article discusses the calculation standard of boiler feedwater enthalpy value.
As a kind of equipment that needs to be used continuously for a long time, it is quite common for the boiler to malfunction due to operation errors or environmental quality problems. Today, Let’s discuss the causes, analysis and solutions of common faults of steam boilers.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
According to the characteristics of biomass fuel, the biomass boiler produced by ZOZEN Boiler has been specially designed in structure, which has taken the lead in solving the problems such as furnace arch collapse, furnace door burn-out, hopper fire and stopper coking.
The boiler water film dust remover uses dust-containing gas to impact the inner wall of the dust remover or other special components, and forms a water film in some way, so that the dust in the flue gas is captured by the water film, thus purifying the gas.
The ignition system of gas-fired boiler adopts high-energy igniter, which belongs to low-voltage capacitive discharge device. Its main structure is composed of nddh high-energy igniter, nddz igniter and nddl shielded ignition cable.
