How to pick a good quality energy saving 4t boiler cheap armenia after the Spring Festival, as the footsteps of spring, the weather will be getting warmer, but still occupied Henan sky haze, boiler plant today to explain how to select energy saving boiler? Energy saving boiler how to select, first look at fuel boilers. How to select energy saving boilers, first look at fuel boilers. Fuel gas-fired boiler used as bituminous coal, lignite, coal culprit is called fog and haze, so the gas boiler can not be called environmentally friendly energy-saving boiler. Fuel oil-fired boilers using heavy oil, compared to a gas boiler, has a capacity of environmental protection, but be aware that the boiler blowdown measures, and therefore there is a certain air pollution. Biomass fuel boiler is called energy saving type boiler, the main fuel is a biomass fuel particles, which fuel is free parathion, does not produce sulfur dioxide and phosphorus pentoxide combustion, and thus will not cause acid rain generation, do not pollute air, not pollute the environment, thus greatly easing the greenhouse gas emissions, to purify the air played a very good effect. Therefore, energy saving boiler how to choose? First look at the use of fuel boilers, so according to this aspect, you can determine what type of environmentally friendly energy-saving boiler.
It is reported that in March 15, Chifeng City, a special inspection of the pressure to carry out an internal inspection of industrial gas and steam 4t boiler cheap armenia upgrade skills than the ability to test cum activity. Chifeng City, the special prosecutor, deputy director Jiao Wenxiang, deputy chief engineer Wang Shusen, deputy chief engineer Zhang Yulin and a pressure test of all personnel to participate. The ratio of the activity is divided into document review, site inspection, inquiry exchange three links, the city of Chifeng hotel comparison site inspection in WNS4-1.25-Q type of boiler.
In the field, compared to persons in accordance with the "boiler periodic inspection rules," "Boiler Safety Technology Supervision" and other relevant standards, test preparation equipment industrial gas steam boiler inspection, the document review, site inspection programs, projects, methods, inspection found defect assessment and treatment, inspection records and test the views of notice to fill in field operations and other aspects of comparison. Then the referee group of inspectors to participate in the comprehensive assessment ratio, the final nine inspectors compared the results were satisfactory. The ratio of inspectors to participate have said, by building a mutual learning platform for the exchange ratio of activities to enhance their own inspection techniques, in order to better carry out the annual inspection lay a solid foundation.
After comparison, the assessment team for each ratio of staff present in the actual operation problems raised rectification, so that each person than to recognize their lack of inspection in the presence of, as well as their ability to enhance the tailored inspection Program. In the future, I will continue to strengthen and enhance the inspection capabilities, adhere to the bottom line of thinking and problem-oriented, to provide a solid technical support for the safety of special equipment to hold the bottom line.
Some of the causes direct impact on the thermal efficiency of horizontal steam 4t boiler cheap armenia 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.
1, the safety valve should be mounted vertically in a high position in the pot business, set box.
2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.
3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.
4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.
5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve.
6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.
7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.
