biomass water heater boiler
Biomass hot water biomass water heater boiler for heating company is one type of hot water boilers.the fuel of the hot water boiler for heating company is concentrated in coal and other fossil fuels for a long time,coal combustion produces carbon dioxide, sulfur dioxide, dust and other pollution gases and suspended particles,form the greenhouse effect and produce the haze phenomenon.With the adjustment of energy structure,the traditional way of industry development which is rely on burning fossil fuel and bring air quality damaged will be eliminated,the biomass fuel supply to hot water boiler develop rapidly.
4 large superior protection systems protect the water steam biomass water heater boiler steam boiler is provided with two pumps, run and standby. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Boiler plate with one or two level timing, should always be compared with each other, find instruction inconsistent, it must be corrected immediately. Each class should rinse water level gauge to determine its true level. And also has balanced water pipe poles can accurately capture level signal or alarm to the pump control. 1, a pressure protection when the boiler pressure exceeds the vapor pressure protection rating, it is necessary to chain protection: is shutdown, the system stops the combustion; nozzle can be replaced, a single stage or two stage combustion, the amount of oil can be adjusted. , thereby reducing the pressure to ensure the safe operation of the boiler. As water pressure protection with protective oil (gas) steam boilers, the use of multiple protection: (1) the pressure controller typically uses two pressure control pressure signal into an electric signal electromechanical conversion device, which is a function of the high and low pressure signals to electrical switches, and the automatic control circuit or an external interlock protection. Normal pressure controller and make electrical contact pressure gauge vapor pressure and overpressure alarm off burner limit is reached, the pressure controller adjusts single or double fire burning fire based on the actual pressure. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. (2) is the last line of defense to protect the safety valve of the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, releasing exhaust pressure, in order to ensure the normal operation of the boiler. 2. Temperature protection is an important part of the process of the safe operation of the boiler, especially for steam boiler temperature regulation and protection. While achieving regulation and protection function of the hot water boiler superheater. Conventional boiler temperature protection means is a bimetallic temperature controller 3. Flameout protection against furnace explosion. Oil (gas) boiler must be equipped with flame protection device, and its function is combustion monitoring furnace (including an ignition when the ignition failure or extinguish combustion, typically re-ignited within five seconds, runs in one second, closed oil ( gas) solenoid valve, is opened concurrent silent alarm signal, the blower continues to operate at this time. after the furnace was purged of combustible residual gas, after purging two thirty seconds, the fan and various auxiliary power cut off, stopping the boiler operation.) by a flame monitoring device and control components. Flame monitor display function is to signal the presence of a flame or an interrupt from the control device. Its main purpose is a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an ultraviolet or infrared type photoelectric conversion element, its working principle is converted to the corresponding light radiation intensity of the high current and low current. And a linear output state, the induced current is sometimes weak, and thus affect the controller amplification. 4. The self-locking power failure protection in case of sudden power failure, the boiler operation immediately closed self-locking, if the current power is restored, start at any time, must be reset to unlock in order to re-start the ignition. Imported monochrome color touch screen control system, fully automated operation. Having automatic water supply, water, over-temperature, over-voltage, automatic power failure alarm, leakage protection security systems.
SZL series chain grate biomass water heater boiler, packaged boiler, can burn mixed fuel like biomass and coal. As to SZL series chain grate boiler, it is a kind of double drums water tube boiler. Brick factory client can use it in brick production process for steam generation.
Hebei Cangzhou issued a "special program on the implementation of standards of governance biomass water heater boiler." Emission standards for boiler treatment and corresponding indication made, as shown in details as follows.
First, the standard standard coal-fired boiler
1, before the end of September 2019, within the city of more than 35 tons of steam / hour ultra-low emission coal-fired boilers complete transformation, emissions of major pollutants to achieve ultra-low emission standards (dust ≤10mg / m³, SO2≤35mg / m³, NOx≤50mg / m³).
Before the end of the year 2/2020, the city eliminated 35 tons of steam / hour and coal-fired boiler, stove and stove operating a small coal stove, achieved within the city 35 steam tons / hour and the boiler "No Coal." Reserved 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove implementation of the special emission standards (dust ≤30mg / m3, SO2≤200mg / m3, NOx≤200mg / m3).
Retention of more than 35 tons of steam / h coal-fired boiler to install air pollution automatic monitoring facilities and networking with the environment department, to install a distributed control system (DCS system), real-time monitoring of pollutant emissions.
Second, gas-fired boiler
1, before the end of September 2019, the city completed two-thirds of the total number of units of low-nitrogen transformation gas boiler above. Among them, the central city of all gas-fired boiler and all the city's industrial and commercial gas-fired boilers to complete a full rebuilding mode low nitrogen.
2, the end of June 2020, the conventional gas boiler should be completed by transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxide respectively 5mg / m³, 10mg / m³, 30mg / m³.
Third, the task
1, increase clean energy alternatives. In areas not covered by central heating pipe network, and vigorously promote geothermal, wind, solar and other clean energy, in an orderly way from coal to gas and coal to electricity, to change the power-based. In 2020, under the conditions of gas supply has been guaranteed, the city eliminated 35 tons of steam / hour and below the coal-fired boilers.
2, increase the coal management and control efforts. Coal infrared video monitoring devices to increase coal quality sampling efforts, to retain the blast furnace coal-fired boilers to be installed, Hebei coal to meet local standards "Industrial and domestic fuel coal" (DB13 / 208102014) non-coal power generation industry quality indicators .
3, strict new boiler access. Ⅲ class urban area and high-pollution fuel combustion zone ban municipal government designated a ban on new coal-fired boiler, a citywide ban on new 35 steam tons / hour and coal-fired boilers, the new 35 steam tons / hour of coal-fired boilers must in line with the municipal government of central heating planning or construction of industrial parks planning, energy efficiency reached AQSIQ "energy-saving technology supervision and management procedures boiler (TSGG0002-2010)" requirements, encourage the use of "energy efficient boiler promotion List" reached the level of energy efficiency standards boiler, pollutant emissions to meet emission standards require extremely low.
