2018, the Group's focus on employee unions difficult. Before and after the traditional festivals, union members of the Group figure active in the employee's family difficulties; a sudden and serious illness died of the scene, the group will always be union members on behalf of the company employees a timely manner; in the process of foreign aid in the public interest, Labor union also took up the banner of love passed.
Laundry hotel special reference to the current selection of steam boilers Hotels generally use the hot water boiler for heating and sanitary hot water, kitchen utensils gas can be directly used, but still need to supply steam laundry room, laundry room steam supply pressure to be 0.4-0.6 MPa, generally an amount of steam in the hotel laundry 0.5 ~ 2.0T / H, steam day with about 3 to 10 tons. Under the premise of the city's coal-fired boilers can not be used, the choice of energy sources natural gas, diesel, liquefied petroleum gas, electricity, in what exactly it is more appropriate? First use to compare the cost of various energy sources, according to Henan hotel energy prices, natural gas is 3.0 yuan / Nm3, diesel 9.0 yuan / kg, liquefied petroleum gas 15 yuan / Nm3, the price of 1 yuan / kwh. Compare 1 ton of steam produced by a variety of energy costs as follows: Energy Category Energy calorific value of natural gas in energy costs per ton of steam 8600kcal / Nm380m33.0 yuan / Nm3240 yuan / ton diesel 10400kcal / kg66kg9 energy consumption per ton of steam energy prices. 0 yuan / kg594 yuan / ton liquefied 22000kcal / Nm331m315 yuan / Nm3465 yuan / ton electric 1kwh700kwh1 yuan / kwh700 yuan / ton Note: energy consumption efficiency estimated by conventional steam boiler; Nm3 refers to the standard state volume of gas M3; calculated from the above analysis, the use of natural gas per ton of steam lowest cost, most economical operation, electrically heated steam up costs. Gas steam boiler typically 2 to 3 sets of selection, single nominal amount of evaporation 0.5T / H ~ 1.5T / H. Gas-fired steam boiler boiler range belong to the state regulators, the need to build a separate boiler room, not like pressure hot water boiler as the main building or in the basement, while the city hotels are often difficult to have a location to build a separate boiler room. In recent years, there is a new type of gas steam boiler, the water capacity is small (less than 30L), a single evaporation accessible 1T / H, do not belong to the state boiler steam boiler regulation range, can be in the basement, a good solution to the conventional steam boiler no suitable location problems.
Distinction gas steam boiler and a conventional coal-fired boilers and gas steam boiler (1) in a conventional coal fired boiler should be prechamber through grinding equipment, coal should be produced for combustion injected into the furnace, the entire combustion process in furnace and in the form of a suspension. (2) as long as the gas steam boiler biomass fuels open, dried and crushed, the helical feeder to the air before it is blown into the top of the combustion grate vibration. After burning the soot removed from the baghouse gas steam boiler. 2, different air supply preheating. 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 (1) coal-fired boiler air preheater flue at the bottom, below the economizer; using flue (2) temperature of the air supply end of the cigarette is heated, different from a conventional boiler, the feed gas steam boiler air preheated by the air preheater flue gas cooler and the two parts to feed water as a medium to absorb heat of the flue gas, conveying air into the furnace. Warm air supply system for a gas steam boiler is controlled by adjusting the supply air temperature of the heating water flow can be provided by adjusting the electric charge of the bypass track circulation water through the valve and the air preheater flue gas cooler bypass control. Water heat exchange section, cooling water heated through the air preheater and the cold air delivery fan; then, this part of the water continues to flue gas cooler, flue gas by exchanging heat with water in the flue gas cooler, water heating, cooling the flue gas. In the bypass, a bypass flue gas cooler and another bypass air preheater, both have their own electrical control bypass and isolation valves. When the flue gas cooler exit gas temperature is too low, the bypass isolation valve is opened, water does not pass through the flue gas cooler, flue gas heat exchanger is not performed to ensure the flue gas cooler outlet gas temperature is not too low smoke corrode gas cooler. In order to enter the flue gas cooler feedwater temperature is not too low, when the air preheater outlet water temperature is below a certain temperature, it opens the bypass, supply cool air can not be heated, the water temperature is too low to prevent the influence of the flue gas cooler work . But also to ensure the temperature of the flue gas through a gas steam boiler precipitator. 3. The coal-fired boiler flue gas fired boiler bag filter should be used for desulfurization libraries to ensure the emission of pollutants lower than the standard. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. However, biomass combustion flue gas are different. Biomass fuel of low sulfur and nitrogen content, only through the biomass filter before discharge into the atmosphere. However, the carbon content of fly ash produced by the combustion of biomass, coal-fired boiler boiler efficiency is better, but the carbon dioxide content in the greenhouse can be reduced. Under the same nitrogen content of the fuel, the nitrogen oxides emission concentration of boiler far below the emission standards for coal-fired boilers. The problem should be noted that operation of the gas boiler. From the operational perspective view of the gas boiler, the operation of the gas boiler should note the following: The actual fuel consumption of the boiler operation, the amount of oil to the adjustment screw feeder. Unburnt fuel in the furnace, induced draft fan and the blower can not be stopped. Sudden power outage in operation, must be promptly removed fuel furnace. Not add biomass fuel before the shutdown. When the furnace stopped, there is no need of the bank up a fire. When the fuel on the grate exhausted, drum induced draft fan may stop running.

I recently moved and the new house has oil heat, buderus oil hot water boiler (6-8 years old) and a stand alone electric hot water tank. The hot water tank has been a rude awakening to my electric bill and with all the masssave rebates out there I'm wondering if it makes sense for me to replace it with either a hybrid/heat pump electric tank or an indirect tank to run off the oil buderus boiler.Get A Quote
