When the pressure of the wet back oil steam boiler protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.
Laundry hotel special reference to the current selection of wet back oil 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.

Small wet back oil steam boiler Description: Small steam boiler refers to the amount of evaporation per unit time is small and low steam pressure steam boiler, steam boilers generally small volume refers to less than 30 micro-liters exemption steam boiler, the mechatronic device, host auxiliary integrated, easy to use, simple to install, simply connect the power, water and heat can, installation, use and technology supervision department supervision is not. Working principle: Its basic principle is: by an automatic control device, to ensure control liquid during operation or high, medium and low probe feedback control electrode opening of the pump, is closed, the amount of water the length of time the heating furnace; it is set by the pressure switch with the constant maximum output vapor pressure steam, the water level falling furnace, when in the low water level (mechanical), water level (electronic), automatic water pump, to the high level, the pump is stopped replenishment; At the same time, the electric tube furnace heating was continued, a steady stream to produce steam, the upper portion of the top panel or instantly display the steam pressure gauge pointer value, the whole process can be automatically displayed by the indicator. Product: Small steam boiler in accordance with the fuel can be divided into small electric steam boilers, small fuel steam boilers, steam boilers and other small gas; in accordance with the vertical structure can be divided into small steam boilers, horizontal steam boiler small, mostly single small steam boiler , double the return of the vertical structure, large steam boiler three-pass mostly horizontal structure
