combined gas fired condensing boiler manufacturer
Combustion conditions provides rapid and substantially complete combustion of 1, a relatively high furnace temperature: the chemical reaction is the basic condition of combustion, fuel ignition and stable combustion, burn have a significant impact, maintaining a suitably high temperature furnace to important. Of course, when the furnace temperature is too high, consider the problem of slagging combined fired condensing boiler manufacturers. 2, the air supply amount: the amount of air supply, is to provide enough oxygen for the fuel, which is the original conditions of the combustion reaction. Air supply, fuel not get enough oxygen, it can not achieve complete combustion. But excessive air, the furnace temperature will lead to loss and exhaust loss increases. 3, good mixing conditions: Mixing is an important physical conditions of the combustion reaction. Mixing the hot flue gas in the furnace is heated to reflux of the pulverized coal flow, so as to rapidly fire. Mixing in the furnace is strongly perturbed stream to provide oxygen to the soot combustion stage surface, outward diffusion of carbon dioxide, and to promote post-combustion of the fuel burn, it is an indispensable condition. 4, enough burn time: the fuel in the furnace for a time sufficient to achieve a high degree of fuel burn, which requires a large enough volume of the furnace. Proportional to the volume of the furnace and boiler capacity. Of course, the furnace volume is also characteristics of the fuel combustion, easy to burn fuel, furnace volume can be relatively small. For example, the same capacity of the boiler, furnace volume of fuel than pulverized coal furnace is small, and vanished without burning furnace volume than coal burning bituminous coal furnace volume slightly larger.
Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, combined fired condensing boiler manufacturer flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
Some of the causes direct impact on the thermal efficiency of horizontal steam combined fired condensing boiler manufacturer of the country are carrying out a blaze of glory roaring coal to natural gas operations, the choice of horizontal steam boiler, greatly reducing the fine dust contaminated with dust, along with toxic gases such as nitrogen oxides emissions It has also been suppressed. Thermal efficiency is a key measure of horizontal steam boiler, a good start and that is that let you look at some of the causes direct impact on the thermal efficiency of horizontal steam boiler. Through research departments, the heat loss of horizontal steam boiler is very important from two aspects: the combustion air-fuel ratio is not satisfactory and Smoke and heat loss. Smoke and heat loss reduction should be modified in the tail horizontal steam boiler soot waste heat recycling install, or choose would be more leading series condensing boilers. Combustion air-fuel ratio over the substandard Analysis: common horizontal ejector-type steam boiler burner choice, without the formation of air-fuel ratio can be flexibly adjusted. Most of the horizontal steam boiler selected non-automatic strong emission burner, leading to the root causes of unsatisfactory air-fuel ratio has the following areas: air-fuel ratio is not ideal is more important is divided into two kinds of probability: When an excess of oxygen, there will be endless excessive cold air is heat conduction, resulting in increased energy consumption horizontal steam boilers, hot horizontal steam boiler efficiency decreased; when oxygen is not standard, incomplete combustion occurs, generating heat horizontal steam boiler efficiency decreased.
With the development of economy and social progress and the improvement of people's awareness of environmental protection, coal-fired combined fired condensing boiler manufacturers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers, oil-fired boilers, gas-fired boilers, and so on. The operation of electric heating boilers is the most expensive, and gas-fired boilers need to be opened with gas pipelines. Then, if there is no natural gas pipeline and the operation cost of the boilers is expected to be low, only the fuel-fired boilers are heated through burners, and the fuel-fired boilers are heated through burners. Fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving.
