electric heating steam boiler supplier
What is different from the hot water boiler and steam boiler there? There are many companies will operate on steam boilers do this relatively high cost of care. After the scene since the late boiler equipment, equipment up and running is a big sum of costs. About enterprise, if choose for their own fuel boilers, boiler fuel efficiency will make use of further progress. Therefore, we demand that the cost of running on several different fuel steam boilers budget to know. Gas: Advantages: clean energy, high thermal efficiency, low cost. Disadvantages: gas adapter constrained condition. Produce one ton of steam costs about 240 yuan (gas prices by 3 yuan / square meter accounting). Fuel: Advantages: no pollution, high efficiency, no fuel constraints. Disadvantages: higher operating costs. About 594 yuan one ton of steam production costs (fuel prices accounted for 9.0 yuan / kg). Electric heating: advantages: no pollution and no fuel constraints. Disadvantages: is a secondary energy, high operating costs, the cost of producing one ton of steam is about 700 yuan (price 1 yuan / degree). Coal: Characteristics: low operating costs. Disadvantages: severe pollution in some areas, the use of restraints, cost of production of one ton of steam is about 150 yuan (coal prices by 1,000 yuan / ton accounting). Heat boiler is an important means to transfer heat to the appropriate fuel equipment, it is now being widely used in industrial production and heating and so on. Popular in the size of the boiler is a steam boiler and hot water boiler both types, many people who only know the boiler heating equipment, but can not tell in detail parting boiler. Today we gave Shandong steam boiler explain what the differences steam boilers and hot water boilers, after all, what! On the surface, we can understand heating hot water boilers and steam boiler heating method chosen is not the same, but the distance between the hot water boiler and steam boiler Moreover, detailed in what areas? The different output media we literally can be seen, the medium is hot water output from the boiler, medium boiler steam output of the steam. First, the user can according to their demand for the output media, choose the appropriate boiler. Different steam boiler space occupied by a high pressure vessel, through steam forming water is heated after the completion of the vapor compression heating, and the area of the pressure vessel by the use of less water boiler is an unpressurized vessel by virtue of heat temperature of the water to complete the heating, hot water boilers professional usually occupied by a larger location, but better able to complete the non-selection of the pressure vessel safety are better able to ensure the safety of those who use. Because the size of different heating and heat storage capacity of water vapor from a large, high-volume hot water boiler and thus be able to choose long-distance transport of heat pump delivery lost less able to complete large-scale transport of hot water requirements. The steam boiler because the steam freezes faster, so in the long-distance transport can lead to sudden drop in water temperature, so the size of two kinds of heat supply boiler equipment can withstand different. Heating steam boiler at different speeds when using the heat generated as the water transpiration and thus burn calories in order to ensure the needs of large steam generation, and thus the temperature rise faster fever faster speed; hot water boiler heated water to ensure that the temperature of the water in the use of Yung heat better, thus better able to maintain the heating heat.
This year, located in Guizhou Tongzi County and located in Heilongjiang Harbin has two boiler explosions accident, after investigation, the accident was produced in the installation link, there are companies the main responsibility for the implementation of incomplete installation link, confusion installation and construction management , unauthorized commissioning, pressure testing irregularities, installation supervision and inspection to ensure the role of the missing and other problems, leading to a boiler explosion occurs, causing adverse effects for the personal and property safety.
Market supervision bureau to draw lessons from the accident, in order to avoid explosion due to boiler installation problem from occurring again, issued a notice warning of the risk of boiler installation link. Details are as follows:
The boiler safety related technical specifications, the entire boiler manufacturing unit can be installed (set) mounted boiler units produced. Boiler manufacturing unit undertake installation work, should meet the following requirements:
The manufacturer should be dedicated departments boiler installation work, set up to cover the boiler installation quality management system, equipped with the necessary resources to installation conditions. Boiler manufacturing units should strengthen sales management, through specified in the sales contract if the terms of the unit responsible for the installation of boilers, etc., to prevent sales by the manufacturing license qualification units or organizations which are not allowed to undertake the unit personnel to carry out boiler installation work. Where specified in the contract manufacturing sales unit responsible for the installation, on-site installation work must be sent by the company to complete the installation personnel shall not be subcontracted to other units (safety specifications are allowed in the assigned project except). Indicate the sales contract to this unit responsible for the installation of the boiler, installation of the unit must have the appropriate license installed. Responsible for the installation of the units should strengthen safety education and skills training for installation personnel. Find that the installation quality and safety aspects of the occurrence of an accident or appears illegal activities, special equipment safety supervision institutions should be punished according to the law to install the unit.
Boiler installation units should strictly enforce the relevant safety standards and technical specifications to ensure the quality and safety of boiler installation, the unit should be installed at the installation site set up signs stating the name of the license holder of the certificate, license project, license number and items the person in charge, who is responsible for safety and quality, commissioning personnel, supervisory inspector's name, unit and telephone. Boiler commissioning and commissioning, operation must be performed by a licensed boiler operator. Before the boiler installation, inspection and acceptance by the relevant formally delivered, installed units should be hung in a prominent position boilers warning signs with the words "banned" and take effective protection and quarantine measures to ensure that the boiler system can not be ignited or boost . In addition to the need to debug, the cabinet can not be energized, the fuel valve is in a closed state should be like. Use blanking panels of the boiler pressure test, the test should be removed immediately after the end of the Blind.
Boiler boiler installation situation before construction units should be installed by informing the local special equipment safety supervision and management departments, and submit an application to install Supervision, Inspection and supervisory inspection agency. Where Supervision and Inspection uncommitted boiler installation project may not start.
Supervisory inspection agency should be strictly in accordance with the "Boiler Inspection Rules", according to the supervisory inspection protocol and progress of the project requirements, arrangements for the implementation of the supervisory inspector boiler installation supervisory inspection. A class of control points, the supervisory inspector must be at the scene confirmed to meet the requirements, the installation unit in order to continue with the work. Supervisory inspector shall, at the start that is to the construction site, in the whole process of site supervision to pressure test, shall not be used after the witness confirmed that and how do fill supervisory inspection program Supervision, Inspection and replacement process when the boiler pressure test.
Boiler manufacturing unit in particular is responsible for boiler installation of manufacturing units and boiler installation supervisory inspection agency, should an accident lessons learned, giving top priority to further implement the main responsibility and checks responsibility, strengthen the boiler installation management to ensure the quality of the installation work, protect the boiler safety.
Depending on the operating characteristics of electric steam boilers, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
Components of the gas steam boiler There are several both production and life, we often gas steam boiler is used, and therefore the author gave us sort out what the associated structural gas steam boiler. First, the blowing apparatus: the blowing device placed inlet filter, through the use of extraction air blower burner was added to achieve an amount of change fire. Second, the water pump: main condenser is pumped from the water softener is then added to take thermal efficiency steam boiler flue gas emissions caused by water once preheated. Third, the fuel gas system: an interface comprising natural gas, burner, natural gas adjusting means. Fourth, the protection valve: placing a certain pressure value, higher than the preset value independent relief. Fifth, gas steam boiler electric control system and other in front of these two would certainly be an integral component of a gas steam boiler, assumptions made when the boiler water quality standard deviation, is not to turn the boiler, should pay close attention. At the time of manufacture, and should always check the gas steam boiler maintenance, maintenance inspection time for serious recording, only careful and thorough use, unswerving overhaul inspection, to be able to increase production efficiency to a greater extent, not only negative results can occur .
