How to choose energy saving gas heating boiler? Most of the field of construction, industrial, life needs to be heating boiler, then what the election or steam boiler hot water boiler heating? How much tonnage, how many? And how to make energy-efficient and environmentally friendly choice of boiler it? These issues will no doubt cause great distress to the customer, the following solve these problems, we can do a simple discussion, consider providing some feasible ideas. A. How to determine the tonnage and the number of boilers must first be calculated from the area of heating and domestic hot water heat demand of the total amount for this issue. Meanwhile, in the calculation of the process, also taking into account factors external architectural features heating areas, temperature characteristics, the peak water heating, etc., due to local conditions at the time. Then, after completing a comprehensive evaluation, will be able to consider the issue of tonnage and number of units furnace, then how should the election, which requires analysis to analyze the results of previous projects using features of the boiler, but also to figure out the actual boiler operating efficiency, as well as tonnage and heat supply matches demand real problem customer site. II. When selected gas heating boilers, steam boilers or hot water is selected by boiler application analysis of many companies, both on a simple comparison, you will find hot water boiler will be energy efficient than steam boiler, so if there are energy-saving project demand, suggested the use of hot water boiler. Of course, both need something like hot water and steam needs, you need to hotels, hospitals and other places to determine the actual situation. If the hot water heating system using a large amount of steam required is very small, it is recommended to configure another small steam boiler or portable 5000 kg diesel steam generator outside of the hot water boiler to meet the needs of a small amount of steam. For example, hospital star hotel or on the amount of steam demand does not exceed 30% of total heat demand, and based on actual experience, in addition to a steam boiler efficiency problem in itself a significant attenuation in the low load operation outside the state, the system energy loss larger, final energy efficiency is generally only about 60%, serious waste of energy. III. How to select energy saving gas heating boiler from the heat required systems, combustion systems, control systems and other consideration, and that is in heat transfer systems, taking into account the use of materials heat exchanger, steel, copper or iron, which according to their comparative property, currently used is copper; combustion system is the key to deciding whether the boiler equipment, energy saving and environmental protection. Current common combustion are: full-premixed, atmospheric premixed and diffusion. But just in terms of energy savings, premix technology would be more advantageous, it pre-mixed air and gas, multi-mode radiator heat, the intensity of the heat transfer improved. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency. In short, the selection of gas heating boiler is a more complex issue, it requires theoretical and practical circumstances combined into consideration before they can get a reasonable result.
With the urban heating developing with a modern, large-scale, centralized heating trend, in 2009, the company bought two 116MW circulating fluidized bed boiler and two bearing generators steam boiler, not only to meet the city construction of rapid development needs, and enterprises to embark on the road of development of cogeneration.
Gas-fired steam boiler meets the requirements of environmental protection biomass fuel is a highly polluting fuel yet? Gas-fired steam boilers can use in the city do? According to environmental requirements and implementation of standards, Chinese Ministry of Environmental Protection has responded, reads as follows: 1. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees gas boiler the ignition system functions to ignite the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. Agriculture and forestry wastes (straw, rice husk, sawdust, branches, etc.) are used as raw materials. Under certain conditions, the use of special equipment for processing rod-shaped, bulk or particulate biomass briquette, can effectively improve the combustion performance of the agricultural and forestry residues, and the sulfur, nitrogen, low ash content, can be used for supporting special combustion equipment, and clean and efficient combustion. It produces sulfur dioxide, nitrogen oxides and soot less, not polluting fuels. Second, the city promote the use of biomass briquettes should take full account of local ambient air quality control requirements and the actual situation of fuel supply. In the case of city gas supply can not meet demand, biomass briquettes as an alternative fuel, fuel-emission standards should be required, and promote the use of scientific evidence in large urban centers, the more stringent requirements on atmospheric emissions of pollutants. 3. In terms of promotion and application of biomass briquette, briquette raw material to strengthen the supervision and management of the production and use of right. Developing local standards and technical specifications and biomass briquette combustion supporting special equipment, which regulate the production and use; in the application process, focusing on the production of dioxins monitoring; production and sales of biomass briquette combustion equipment and dedicated support unit shall have appropriate qualifications. Products should be certified by the quality, safety, environmental protection, energy conservation and other relevant authorities and comply with the relevant technical regulations and standards. Environmental protection is a basic national policy of China. Take the road of sustainable development has become a basic strategy of economic and social development of our country. To further implement the "People's Republic of China Air Pollution Prevention Law," "People's Republic of China Energy Conservation Law" and the "Provisional Regulations on Boiler and Pressure Vessel Safety Supervision." Comprehensive Plan and in accordance with the requirements of the country atmosphere. Natural gas boiler manufacturers strengthened pollution control and energy conservation boiler safety. Gas-fired steam boiler to achieve a low-carbon environmental requirements. Replace coal-fired boilers with gas-fired boilers help save energy and improve the environment, and has been included in the Ministry of Environmental Protection and China Environmental Protection Industry Association, the state's key environmental protection practical technology projects. Boiler is an energy conversion device. The boiler is a chemical energy input fuel and electrical energy, thermal energy output at a certain boiler steam, hot water or organic heat carrier. Pan intended to refer to heating of the water container on the fire, the chamber means where combustion of the fuel, a boiler comprising a furnace and two pot portions. Hot water or steam produced by the boiler can provide the required heat energy directly to industrial production and people's lives can be transformed into mechanical energy through a steam power plant, or by a generator converts mechanical energy to electrical energy. Provide hot water boiler known as hot water boilers, mainly for life, seldom used in industrial production. Boiler steam is known as steam boilers, typically referred to as boiler, it is mainly used for thermal power plants, ships, locomotives, and industrial and mining enterprises.
